Patagonia Nano Puff Pants
Excellent product at the best price found. Excellent transaction with Platte River Fly Shop, all done online. The Patagonia Nano Puff pants were a gift & the recipient loves them. I highly recommend the product and Platte River Fly Shop.

Great for under waders
I originally bought these to wear under my waders during fall and winter in the Blue Ridge Mountains to go Brookie fishing. I haven't had a chance to get up there yet but I have worn them. They're great. The back of them is smart. They'll pair well with my nano hoodie. Hopefully it stops raining so the rivers quit gushing :-). If you have a nano jacket or hoodie you know what to expect. Having them as pants is amazing. If you don't have a nano. It's patagonia. It works like always. Shipping was fast and the service was helpful as always. Thanks for a great experience.

Choice after hours of research
Spent hours researching a good under-wader pant and even for other sports. Pros: Thin (don’t need as much loft as down). Specific rear fabric for durability. Warm (can feel the heat trapped). Comfortable (super light and look good). Warm when wet (essential to water sports). Slick material (helps easy slip on-off for layering). Cons: More like suggestions: zippers for the pockets, cinch or Velcro for cuffs.

Great Piece of kit!
Every now and then there comes along a piece of kit you just need to purchase. These Nano Puff Pants fit that category. When you need them . . . you need them. They have lots of uses, but for me I'm able to reduce & lighten up my bikepacking gear. Able to take a lighter sleeping bag, they fit over my cycling shorts for those colds days, great when off the bike to keep warm, etc. I'm 5'9" 170 lbs and the Med fit perfect. Fit true to size and have the excellent Patagonia quality.
