Additional Information

Unlike any midlayer bottoms you’ve ever worn, the Nano-Air® Light Pants deliver warm, stretchy, breathable performance for moving fast in cold climates.

Read More Close
Stretchy, warm, snow-shedding and breathable, our Nano-Air® Light Pants introduce a new concept for moving fast in cold climates. We designed these pared-down, pull-on pants as a midlayer, though the fabric package extends their range of use in all directions: they excel whether worn alone, under or over layers. The ultralight,100% nylon stretch shell and liner resists weather and fits with layers, yet the superb breathability and light insulation (40-g FullRange® insulation) lends unprecedented versatility. The elasticized waistband has an internal drawcord adjustment, and the invisible crotch zip (with 2-way head-to-head sliders) pairs with the Galvanized Pants for full alpine performance. The polyester/spandex stretch-woven cuffs are shaped and patterned to push up easily, and either stretch over or tuck into an alpine boot. The simple, no-pocket design is patterned to reduce bulky seams and maximize stretch in this slim-fitting silhouette.
  • Light yet durable 100% nylon ripstop shell and plain-weave liner, both with a DWR (durable water repellent) finish, offer generous mechanical stretch and exceptional breathability
  • Revolutionary 40-g FullRange® insulation warms and stretches; combined with the shell and liner, this creates excellent mechanical stretch and unprecedented air permeability (70CFM)
  • Patterned to reduce bulky seams and maximize stretch in a slim-fitting silhouette
  • Pull-on pants with elasticized waistband and internal drawcord adjustment
  • Zip-through crotch has 2-way, head-to-head sliders for easy pit stops
  • Stretch-woven cuffs are shaped and patterned to push up easily, and either stretch over or tuck into an alpine boot

Water Resistant

DWR (durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.

Women's Nano-Air Light Pants is rated 4.0 out of 5 by 8.
Rated 4 out of 5 by from I for one am excited about the zipper I usually wait until after I try gear out to provide a rating. I'm posting now because I am so excited about the zipper, and saw a bunch of anti-zipper comments. Patagonia, please consider creating other pants with crotch-zipper/opening options. As I'm sitting here typing, I can't feel the zipper.

Rated 4 out of 5 by from Great insulating layer My review echoes the others. I love wearing these pants over a wool baselayer for extra warmth around camp at night. They are really comfortable and have a great warmth-to-weight ratio. However, like the other reviewers, I also find the crotch zipper ridiculous since the rest of my 'system' doesn't have one and thus makes the feature useless. It would be great if Patagonia could make a zipper-free version going forward.

Rated 4 out of 5 by from Excellent insulation, but the zipper.... I purchased a pair of these pants before a trip down the Grand Canyon in January in a packraft for an extra layer under my drysuit. They are AWESOME in terms of warmth, and they are not bulky or bunchy at all. I would totally give these pants 5-stars except for the crotch zipper - it wasn't noticeable comfort-wise, but it is just extra, unnecessary weight. If you don't have a full system of zip-crotch clothing (long johns + drysuit, etc.) then it is a totally useless feature. I would have much preferred having 6" ankle zips on both legs so I could get these on and off easily over my shoes in camp.

Rated 5 out of 5 by from Incredible!!! I tried these on in the Ventura store as a joke - because we thought the bum to crotch zipper was hilarious. However, as soon as I put them on I was sold - it felt like I had encased my legs in their own sleeping bags! SO comfy and warm. I bought them and have literally worn them almost every single day I've been home (in the PNW) for working outside. My whole body stays warm - I've never had a layer for my legs like these - I can't recommend them enough. My only wish is that Patagonia made an equivalent pair without the zipper. I never use it and though it doesn't bother me, it does add a bit of bulk. Otherwise, these are the perfect outdoor work pant for the shoulder seasons! *For fit guidance, I think they run big - I'm 5'8", 138lbs and I fit into a Small.

Rated 4 out of 5 by from Super Warm and Comfortable! These pants are awesome. I wore them camping this winter in the Boundary Waters in Minnesota. The are comfortable to spend the day in and sleep in. The only thing I don't like it the zipper. Not practical since I was wearing a layer under these.

Rated 4 out of 5 by from comfortable all purpose pants Pants are great for multiple uses. I'm 5'5 125lbs and bought a small. The length is perfect. The butt area is a little baggy, but this provided ample movement for xc skiing, which is why I bought them. I'm able to wear a wool base layer underneath and they keep me plenty warm and dry even during a light Montana snow fall.

Rated 3 out of 5 by from Very warm I wear these pants skiing and they are really great. Very warm and comfortable. The MAJOR con is the crotch zipper. I don't have other pants to utilize this function, so it serves no purpose, only gets in the way. A zipper between your legs is not always comfortable,either. I hope Patagonia develops these pants without this feature in the future.

Rated 4 out of 5 by from great camp pants I wore these on a month-long arctic trip this fall. I'm 5'10''/140 lbs, and L was good for layering but not over-long; anyone taller might find them floods. These were awesome for throwing on over long johns in the a.m. to do morning chores--light and warm. I would probably have rated 5 star except: the crotch zipper is ridiculous! It would only be useful if one were going commando or had a corresponding base layer with a zip crotch. So the zipper added bulk and a weird bulge with no benefit. Keeping it simple with no zips would probably be more appropriate for typical use.
