Like many, I got a puppy in 2020. I had to gear up for morning walks and these nano puff pants are amazing for those early morning walks down in the 30s.

Super Warm, but expecting a different fit
I bought these pants with the intention of using them during my annual fishing ice fishing trip, but also knew I was going to wear them casually during the winter. I am still pleased with the product, i did think that they would fit a little more like joggers- more snuggly to the legs, nit so much like 'pants/ pants'- if you know what i m... Read Moreean.

Good pants but insulation is poking through
I wade fish through the winter months so these pants were on my radar for a long time. I read reviews posted everywhere, not just Patagonia's site, before deciding to purchase a pair on sale from Platte River Fly Shop last November. I have used them for one winter season on roughly 22 trips. The fit is fine for me. I have about a 34" wais... Read Moret and 32" inseam. They are a bit loose in the waist but this allows for layering underneath with one, or more often two layers (base layer plus sweatpants), which is necessary in the heart of winter. Base layer plus Nano Puffs was not sufficient for me during the coldest months if I spent time in knee to thigh deep water. When I needed a snug up the waist I just used a belt off a pair of quick-dry pants I already own. I like the pants for the intended application of insulation under fly fishing waders. The DWR coating on the pants is helpful if your waders spring a pinhole leak. There are few good thermal sweatpants on the market with a DWR finish so the Nano Puff pants help fill that gap. So why the 3-star rating you may ask? I carefully read all the negative comments posted anywhere about these pants. I think many are classified as personal preference (i.e. poor fit for a given person's body shape) or insufficient performance in unintended applications (e.g. use as the exterior layer for hiking). The one comment I do concur with was a guy who reported a problem with the insulation poking through the seat reinforcement material on the buttocks area (https://www.trailspace.com/gear/patagonia/nano-puff-pants/). This Trailspace review was posted 5 years ago so this problem is not new. On my pants this began to happen after the very first use and has become progressively worse over time. It is also strangely more severe on the left side than the right, which also suggests to me that this is not normal. The problem has not seemed to progress on the right side. I have a Nano Puff Jacket and there are a couple isolated spots where one strand of insulation is poking through, nothing compared to what I'm seeing on the pants. I have not yet washed the pants so who knows whether this will get worse after doing so. Overall, I like the pants. They have provided good insulation under my waders without the bulk of ski pants, which I have used in the past. Whether the problems I'm seeing are just cosmetic or might actually reduce the overall life and function of the pants is as yet unknown. Nevertheless, for a high-end product with a premium price I expect better quality. Hence, I was forced to give this product a lower rating.

I wear these over a pair of jeans and under a canvas bib pant, and I am good to go outside at -40 degrees all day. they do not restrict movement and have great insulation properties whether standing around an instrument, going miles on a snowmachine, or hiking on the tundra they regulate heat very well.

Not Made for Ladies
These are very expensive to not fit a woman’s body as well as their other winter clothing.

My new favorite pants
These gems aren’t just for cold winter days on the river. They’re perfect under waders but the same holds true for anytime comfort and warmth matters. I’ve found myself turning down the heater just so I can keep them on while lounging around the house. At just under 5’8”, 155 lbs., and a 31” waist, the small fit perfectly.
Nano Puff Pants
These pants are amazing. I wear them under my waders for fishing in ice cold water. Or sitting on the boat all day in the cooler temps. They are warm and function very well. I would have given a 5 star review but the sizing was a bit off for me. I am 6 feet tall and have a 34 inch waist. the large was big in the waist and super long, I have to rol... Read Morel them up. I ordered a Size M and they were better in length but too tight around my waist. So I kept the size Large and roll them up a little bit. Overall these pants are amazing.

I Dream of an Ankle Zipper
These pants are the cat's knees. Wow I love them. They have replaced my sweatpants around the house, and are perfect to wear over my dress pants on the way into work. The waist is a probably right (I got a Large, have a 33" waist) however length is spot on (6'1). I got the Large as I read that they run a bit short and I would say tha... Read Moret is accurate as I usually wear a medium in pants given my waist size. The pockets are deep as well, which is a nice plus. Like I said in the title, these pants would be the best pants ever if they just had an ankle zipper! Having to take my shoes off to put them on/take them off is a minor inconvenience but it would really be worthwhile, especially for those of us who aren't using them for fly fishing.
these are the (very) distant relative of ultralight down pants with full side zips Patagonia carried Ages ago.

Puffy pants -- woo hoo! But a little too short in the small sizes, even for ladies!
I really wanted a pair of puffy pants for belaying and hanging around cold camps. They are just really hard to find fit for women! So I got these in an XS, and they really are almost perfect for me.

So I would echo other comments (by men!) that these are too short in the smaller sizes. Otherwise they are dreamy warm and really don't look too bad on (as long as I don't look in the mirror, ha ha!). So all of you ladies out there might want to give them a try. Warm legs make a HUGE difference. You will not feel stupid once you are wearing these things.
Lucky Hubby! Need some warmth for women too!
I just ordered these for my husband.... I have a pair of Montbell down pants that have worn out.

Winter Wading Must
These pants are a must have in your arsenal for winter wading. I was out the other day the air temp was 29' degrees in the water temp was 36'.I had my R1 pants as a base over these and was toasty all day.

I had small pin hole leak in my right leg nothing major the DWR coating prevented by base layers from getting wet.The fact they stay warm when wet is a life saver in winter conditions. If your a winter steelheader or just chasing fish cold conditions these pants are a must have !
These pants are so comfy. Weather at home watching TV or out at the bars in the winter or in my waders in the winter and spring. They are designed like a normal pare of pants and I would advise any buyer to wear them like one. You will always be comfortable they are like a fancy pair of sweat pants.
I like the color,fit,pockets and belt loops. I am usually an xs in men's pants but the waist was very small. The small fits great-room for layers. Have worn them in 5-45 degree weather doing outside chores. I wish for a zipper at the ankles as this would make them even more useful to be able to pull over my running shoes.
I'm on the ski patrol for a hill in Wisconsin. I have only needed to use a base layer and these pants under my lower shell to keep warm while patrolling this year. So far the weather has gotten down to about 0 degrees F while wearing these. Below that I have to add a different layer to sit on the chair lift comfortably. If I could have anythin...

Warm and light weight
I bought this a couple months ago for my husband and he has used already in several winter camping trips. It was a great purchase,lightweight,warm and packs small. He really likes the reinforced button and the tigh and bum reinforcement,wished it had also knee reinforcement and a stuff sack though.
Perfect for chasing steelhead in BC
I purchased these for a four day trip chasing steelhead on the Squamish and Skeena in BC in April. They were perfect. My legs stayed warm all day while wading in water around ~40-44 F.

Warm mid-layer for skiing
I bought these pants to add a warm mid-layer when skiing. I prefer to wear shell pants with no insulation and choose the right level of insulation based on the conditions. This winter in southern Ontario has been fairly mild,so I have had a limited ability to test the warmth of these pants; however,on the few cold days we've had,these pants ha... Read Moreve kept my legs toasty with a pair of long underwear beneath. They're quite comfortable and the inner shell makes them a cinch to slip on and off. I know these pants were designed for wearing under waders,but from a skiing mid-layer perspective,I would suggest the following changes for future iterations: - Elastic waist: I'm pretty lazy,so I just want to pull up my pants instead of fiddling with a second button and fly (in addition to my ski pants). - Cuffs: If find the pants are too bulky to stuff inside my ski boots,but the cuffs are a little small to push up and over my calves easily while I do up my boots. I find it's a bit of a fiddle to get the pants readjusted at the top of my boot after my boots are done up. I would either widen the cuff a bit or add a zipper to make the pants more adjustable and get them out of the way of my boots - Women's version: The fist thing my wife said when she saw me in these pants is "I need a pair of those. I'm the one who is always cold". She went looking at a couple of retailers before we figured out they were only available for men and the stores near us only had size S ,which were all too big for her. This was very surprising for me because she NEVER gets excited about new gear,so if these pants can get her enthused about clothing,I'm sure there is a market out there. All in all,I would recommend these pants for anyone who needs a warm lower mid-layer.
Warm in cold conditions
I purchased the Nano Puff pants to use while ice fishing at Lake of the Woods in Baudette,Minnesota. I used them as a base layer under my cold weather bibs. The first morning it was 21 below zero when we headed out on the ice to fish. The second morning it was 20 below zero. Wind chill both days was more than 30 below zero. These pants helped to ke...

I was so excited to see that Patagiona finally made Nano Puff pants. I've been dreaming of these for years.

Another Great Patagonia Product!
As with all Patagonia products, the quality is superior. They give you the ability to buy an non insulated pant and layer it without the bulk for colder weather. I have worn these pants in extreme cold ski conditions (-10 f) and stayed very warm and comfortable without looking and feeling like the Stay-Puffed Marshmallow Man.
It seemed like I was waiting forever for Patagonia to finally release a pant version of their awesome nano puff insulation. However, after trying a pair, I have to call into question the design choices made on this first attempt. My primary intended use was insulation under my waders when fly fishing in colder temps, but the chino-esque design of t... Read Morehe pant makes them too bulky. Why design an insulation layer like a pair of casual wear pants?? The side pockets create too much flair in the hips and the button and zip closure are, in my opinion, the wrong choice as well. When considering my secondary intended use, replacing the fleece tights in my pack for nights at camp in the backcountry, the same questionable design choices resonate again. Why do I want a chino when relaxing in camp? Wouldn't it serve me better for my purposes of fishing and lounging, or other endeavors like climbing or snow sports insulation to have a more streamlined pocketless design (maybe a back zip pocket into which the pants can be stuffed, a feature that's a staple with the whole of the nano puff line) and a simpler waistband (perhaps elastic and drawstring or elastic cord and cord lock). Ideally I'd like to see this product rethought and reworked into something that lines up significantly better with the nano puff collection.
