Patagonia Micro Puff Hoody Review: Creatureless Comfort

As a cold-natured gal, and an ardent animal lover, Virginia was psyched to try out Patagonia’s latest synthetic down jacket, which is touted to have a better warmth to weight ratio than their ultralight down jackets, and be just as compressible. Read the detailed review after she wore it around town and on the trails for the last several months…

Finding the perfect ultralight puffy jacket has always involved some sort of compromise. Natural goose down generally provides the highest warmth to weight ratio of any insulator. It’s incredible loftiness traps the heat that our bodies generate. Down also compresses amazingly well, which is a critical factor when pack space is at a premium. Unfortunately, down has a few drawbacks. It does not repel water, and, when wet, it tends to clump up and lose its ability to loft. No loft= significantly reduced heat retention. Down also dries slowly, so once it’s gotten wet, it takes a long time to recover. Another major “down” fall is its source. Down comes from goose or duck plumage. While there are “responsible” means of harvesting down (see the Responsible Down Standard or Patagonia’s own stringent Traceable Down Standard), lots of folks just don’t feel comfortable wearing a by-product of somebody else’s death.

Synthetic insulation tolerates getting damp much better than down. The hydrophobic polyester fibers maintain their loft and insulating properties, and then also dry more quickly once saturated. Synthetic jackets are also a bit more breathable than down jackets, which adds to their versatility. Often they can provide comfort in a wide range of temperatures, even during active, sweat producing pursuits. But, when it comes to facing truly cold temperatures, jackets with synthetic insulation usually don’t provide as much warmth as down. And, as for packability, they don’t compress as well either.

Enter the Patagonia Micro Puff Hoody. The engineers at Patagonia worked long and hard to create a new kind of synthetic insulation, one they say addresses both the heat and compressibility shortfalls found in many polyester fills. The inspiration for its design… what else… goose down. The insulation, called PlumaFill, looks like a tiny feather boa, and features tufts of heat-trapping ultrafine polyester filament anchored to a single, central strand. Those fluffy offshoots compress like down, but stay warm and lofted when wet. The central strand design was employed to keep the insulation from shifting and clumping. With less shifty insulation, the need for individual baffles was eliminated. Instead, the Micro Puff is quilted with offset blocks of differing sizes. Theoretically, having fewer seams maximizes the efficiency of the insulation, allowing heat to move more freely throughout the jacket, creating a consistent distribution of warmth and preventing the formation of cold spots. So, that’s the science behind the Patagonia Micro Puff Hoody, but does it really deliver on all of its lofty promises?

The Micro Puff jacket packs a lot of warmth into a small package. To be clear, it’s not a parka, but, with a medium weight wool base layer, the jacket has kept me quite comfortable in mid-30 (-1°C) to low-40s (4.4°C) temperatures (°F) while being relatively inactive. Once the temperature drops into the lower 30s, a heavier base layer can be added to lower this temperature rating. What’s really remarkable about this jacket is that it’s also a great piece of gear in temperatures ranging from the mid 60s (15.5°C) to lower 70s (21°C). I guess there aren’t many folks who think about wearing a jacket in 70 degree weather, but, as previously mentioned, I am cold-natured. Often the day starts off really cold and I just forget to take off my jacket until the afternoon, when temperatures start to climb.

Despite some reviews I’ve read to the contrary, I think the Micro Puff Hoody is relatively breathable when compared to similar down fill jackets. I’ve worn the Micro Puff in low-mid 40°F (4.4°C) weather on some pretty grueling climbs. At times, I need to partially unzip it, but my perspiration evaporates quickly. But make no mistake, it is not a jacket purpose-built to breathe well during active pursuits, such as Patagonia’s Nano Air, another synthetic jacket that we reviewed in our roundup a couple years back. As Indiana Schulz — the second place finisher in the American Trail Race — answered when asked about his favorite pieces of gear on the trip, “The Patagonia Nano Air breathes amazingly well. You can wear it while riding and it actually works.” As such, the Nano Air had a slightly different shell fabric, and is pretty heavy (12.7oz/357g) and not very packable as a result. It’s also not as warm, which is where the Micro Puff Hoody shines.

Weather Resistance

In full disclosure, I haven’t submerged my jacket in a pool of water or worn it in a monsoon. Nevertheless, in my day-to-day activities (while living in the rainforest that I call home) I’ve been very impressed with the jacket’s water shedding capabilities. The ultralight nylon ripstop Pertex Quantum shell has a DWR (durable water repellent) finish that allows light precipitation to just roll off the surface. Heavier rain seems to impregnate the shell (at least it looks saturated) without affecting the insulation’s loft or soaking through to the inner lining.

As a natural born skeptic, I imagine that the DWR finish will begin to wear in time. If that is the case, or my plans are likely to get me stuck in a sustained downpour, I’ll most likely throw on a light shell for added protection… something like my Outdoor Research Helium II, which fits quite comfortably as a top layer.

The Micro Puff’s shell also provides decent windproofing. While there are some weaknesses when compared to a garment with no thru-seams, the unique construction of this jacket means those gaps are minimized.

The Patagonia Micro Puff Hoody feels decidedly slimmer than other lightweight jackets I’ve tried, and I mean that in a good way. I am not a fan of Michelin-man type bulk, and I don’t want anything interfering with my range of motion, or the ability to add base layers. This jacket is pretty much perfect in that regard. I generally wear a size medium in any article of clothing, so that’s what I opted for with this jacket. It fits well, not exactly “form fitting”, but that’s not my style anyway. I have room to wear a heavy weight baselayer underneath it and still feel flexible. The no frills elastic binding on the cuffs, hood, and bottom trim provide enough cinch to keep things in place without being at all constricting.


The Micro Puff jacket isn’t flush with fancy features, but, unlike some ultralight gear, its not bare bones either. It has two zippered handwarmer pockets and two deep interior, elasticized drop-in pockets. One of the handwarmer pockets doubles as a stuff sack with an integrated cord loop, so it can be clipped to a pack or harness. In comparison to other jackets I’ve worn, the pocket stuff sack accommodates the jacket far more easily. That saves time and frustration when packing, but it means that there’s a little wasted space in the end. If space preservation is a high priority, an added compression strap or smaller stuff sack may be in order.

The hood, while simple in construction, fits well. It lacks any means for adjustment, so individuals with smaller heads might find that the hood rides a little low on the forehead, but the profile is eased sufficiently to not interfere with peripheral vision…a major plus. Also, as advertised, the hood does fit under my bike helmet.

The women’s Micro Puff comes in four colors… black, Elwha Blue, Feather Grey, and magenta. The men’s is available in black, Forge Grey, Paintbrush Red (which is more orange as you can see in some of these photos), and Viking Blue.

Weight/ Pack Size

Here’s where the Micro Puff really shines. The size medium women’s version weighs in at a scant 243 grams (8.6oz), which is slightly above the 8oz claimed. No other synthetic jacket that I’ve researched can match that. It’s also highly compressible. As previously mentioned, it packs neatly into the integrated stuff sack/hand warmer pocket with room to spare. Fully compressed, it’s about the size of a standard 24oz water bottle. For bikepacking in cool weather, this jacket’s weight and compressibility make it a dream. My previous down jacket provided a comparable degree of warmth but occupied a significantly larger footprint.

Patagonia Micro puff Hoody vs Ultralight Down

When put head to head against Patagonia’s proven Ultralight Down Jacket, there are a couple things to note. First, as Virginia mentioned, she found the Micro Puff to be slightly delicate (although I second the fact that she is rough on gear). That said, the Patagonia Ultralight Down Jacket has a slightly thicker skin. It features a 15-denier ripstop Pertex Quantum shell while the Micro Puff Hoody has a 10-denier Pertex Quantum shell. As far as weight, my non-hooded medium UDJ tips the scales at 257g compared to a medium men’s hooded MPH at 270g. Tack on a hood and the MPH is definitely lighter, and in my opinion similar on the warmth meter. – Logan


With all of its strengths, the Micro Puff Hoody has one substantial drawback. The same element that allows for its incredibly low weight and weather resistance comes at a price. The jacket’s Pertex Quantum® shell is made with delicate 10 denier ripstop nylon. Admittedly, I tend to be a little rough on things, but it’s not like I’ve been wading through thorny bushes or scaling granite in this jacket. Nevertheless, I’ve sustained a few tiny pinholes in a relatively short period of time. Fortunately, they seem to be self-limiting, and, because of its linear design, the insulation is staying in place save a few tufts here and there that need to be trimmed.

All of that being said, this jacket probably isn’t the best choice for rock scramblers or those who want to bundle up while riding through dense brush. But, for those folks who know how to care for their gear and don’t often stray too far into bushwhacking territory during the colder months, the delicacy of the shell shouldn’t be a deal breaker.


  • Lightweight: The women’s size medium weighs in at a mere 243g (8.6oz)
  • Warmth: This jacket holds in a lot of heat in a small package.
  • Packability: It compresses down to the size of a 24oz water bottle, most synthetic jackets don’t come close.


  • Delicate: Most ultralight gear is somewhat delicate, but this shell seems particularly sensitive to abrasions.
  • Price: At $299, the Micro Puff Hoody isn’t cheap. There may be comparably warm jackets at lower price points, but my bet is that they won’t be nearly as light or compressible.

Wrap Up

Patagonia claims the Micro Puff Hoody is the best warmth to weight ratio jacket they’ve ever constructed. While some may argue the proprietary Pluma Fill insulation may not hold on to heat quite as well as down, it’s very very close. And unlike its animal derived competition, the synthetic material stays lofted and warm when wet. The superlight nylon ripstop shell blocks wind and its DWR coating does an impressive job at shedding moderate precipitation. To top it off, the Micro Puff compresses as well as any down jacket I’ve used, weighs next to nothing, and does it all without harming a soul. Its delicate shell is definitely something that needs to be taken into consideration by would-be wearers, but considering most bikepackers limit their puff for hanging out at camp, adding a sleeping layer, or cold rides out of camp in the morning, I think this jacket is a great fit for most bikepacking expeditions.

  • great review, I’ve been waiting for this :)
    how would you compare the micro puff to the nano puff in terms of packability, warmth and durability? is the price difference justifiable?

  • Neither I or Gin have any experience with the Nano Puff, but I’ll chime in re weight/material. I think the Nano would be a little more durable – it has a 22-denier polyester shell. But I think the insulation is inferior as far as warmth and compressibility (based on my experience with the Nano Air) and not quite as warm (it has 60g PrimaLoft). My guess is that it wouldn’t pack nearly as small. And, of course, it’s a little over 3oz heavier — 363 g (12.8 oz) for a men’s medium hooded. If warmth and compression are your priorities, I think it’s probably worth the extra $50, but if you aren’t as worried about space, and something with a more rugged shell suits your style, I would stick with the Nano Puff.

  • Mark Troup

    I think the real world difference in price— Nano hoody vs Micro hoody— is actually a lot more than $50 though. The NanoPuff hoodies (which may be discontinued? they’re no longer on Patagonia’s site) can be had for less than $120 if you keep an eye out for the sales. I think I paid $118 about a year ago. The MicroPuffs are gonna be tough to find for anything less than full retail for a while I think.

    Of course, the bargain bin NanoPuffs will likely be their ass-ugliest colors, but I’m not winning any fashion awards regardless.

  • mebaru

    Nano Puff isn’t durable too. I believe both jackets should be used primary as an insulation layer with hardshell or softshell because they are very delicate and not windproof. For similar features but better durability as outer layer I use OR Uberlayer. Though, it doesn’t pack as small and not as warm (more in line with Nano Puff).

    In regards to Micro Puff, it seems to be very interesting and evolutionary product. The price isn’t great though – $300 for synthetic insulation jacket? I would like to see it compared to down-fill jackets in terms of warmth per weight ratio. For example, MH Ghost Whisperer jacket costs the same (but can be found with great discounts or half-price on Massdrop), weights only 221 g and packs as small.

  • Stephen Poole

    FWIW, I’ve got what IIRC is a Nano Puff hoody, bought earlier this year, and also a Mountain Hardware lightweight down jacket. The MHW is very sensitive to precipitation, which seems to go through the outer shell very quickly and wet the down, making it less effective – not that it’s very warm anyway; I’ve not noticed this with other down gear. It also seems much more delicate than the Nano Puff, not that I’m hard on gear.

    However, the Nano Puff is warmer, the cut, fit and pockets are better, it’s more comfy over a wider range of temps, and a bit of rain ir snow doesn’t bother it. Yes, it is a little bulkier, but it’s a much more useful garment.

    One problem with down is that all the fabric needed to stop it moving around really limits how light or compact things can be, not such an issue with synthetics, or warmer garments.

    If the Micro puff is smaller again, with more pockets, an integral stuff sack plus warmer then that would be excellent, not that there’s anything wrong with what I have. I like Patagonia. ;-)

  • mikeetheviking

    Excellent and thorough review Gin!

    I currently use a MH ghost wisperer. It is super light and super packable. But it is so delicate that I don’t want to wear it for everyday use. I only use it as a tool in my kit.

  • Tim Field

    it would be helpful to quote temperatures in centigrade as well as Fahrenheit as most of the rest of world outside the USA (including me) has no idea about centigrade. From Europe it seems really strange that SI units are not the standard on sites like this.

  • All units on all pages of this site are reiterated in SI. This one slipped as the sentences were a bit odd, but it was mentioned. And I fixed the others.

  • Tony Cambio

    I have a Nano puff jacket that I’ve worn down to zero with a Pearl Izumi wind front jacket over, and a Bontrager synthetic base under.

  • mikeetheviking

    Good to know!

  • Stephen Poole

    ^ That’s the one I have – the Nano Puff is much more useful in my opinion, though bulkier. I don’t think the GW is much warmer than a fleece. It was bought sight unseen, and I’d return it if I could; the Nano Puff is a keeper though.

  • ZoubIWah

    other reviews overwhelmingly agree that this jacket is not nearly as warm as down jackets of the same weight including patagucci’s own nano puff, but you did not really address that – or maybe have not read them. i find it interesting that you’re the only one finding them to be really equivalent

    i myself would question these jackets on the bike though. I feel like they’re not nearly breathable enough and dont perform well when wet (from your sweat, not the rain) even the synthetic micro puff reviewed here.
    Patagucci also has the nano air which is actually great for this. The way I see it, is that the puffy jackets – both down and synthetic – are great *off* the bike if you spend a lot of time off the bike as well, but terrible *on* the bike (also due to durability issue as you experienced)

    being so inadequate for biking am I wondering how this made it to your top gear of the year 2017…

    Here you go: 286g and yes of course you’ll still want an actual rain jacket like the one you mentioned, which is fine (im not even sure why they coat that stuff with DWR.. its not very useful)

    ./yes yet another criticism of your reviews, despite the high quality of the presentation and some of the test being interesting, some of it always seem really flawed

  • I have since used this jacket quite a bit and will chime in. The warmth is impressively close to down IMO. I have a similar weight down jacket (montbell) and took them out on a hikes on back to back days in the low 20s (F). I was surprised that this jacket actually felt warmer than the down. Granted they are not the exact same shell either the same fill, they are close.

    As far as the gear award, we have been impressed with this jacket’s warmth, weight, packability, and the fact that it uses the new innovative plumafill which theoretically has the same heat trapping properties as down but doesn’t require the suffering of animals to make. I agree, this isn’t as much an ‘on the bike’ jacket … but ultralight camping gear is just as relevant to bikepacking — hence the award. As far as performance when wet, while you are right, it is relatively non-breathable compared to a jacket like the Nano Air or 7mesh’s Outflow, this synthetic insulation does still insulate when wet… unlike down.

  • Unfortunately synthetic fibres from these jackets are lost when washed and end up in the sea and return to us via our dinner plates. Hats off to Patagonia as they themselves funded the research into this. It’s obviously a problem with all synthetic fibres. A bit of an elephant in the room for someone such as myself whose bought synthetic everything to try eliminate animal products from my setup.

    Speaking of feathers my last remaining down jacket is an REI 650 fill jacket. It’s useless once it gets wet so despite what I said above I’m still interested in buying a synthetic one as I live in cold wet climes. The nano puff is pretty nice looking but very expensive! Here in the UK I find RAB clothing a very good balance between affordability and performance. Not sure you guys get RAB in the USA!

  • That’s a great point. I saw a statistic somewhere recently (PPM) about how microscopic plastic particles and fibers are everywhere nowadays… due mostly to packaging. Makes one think. Unfortunately, when it comes to insulation (down vs synthetic), there is dark side to both…

  • Agreed. For me personally the issue with synthetics doesn’t make buying down a reasonsble alternative. To this end I suppose I’ll just have to take care of my stuff and try and make it last and not succumb to gear lust unnecessarily. I read that its still single use packaging in which these garments arrive is still the biggest polluter and arguably the most wasteful and unnecessary.
