Patagonia Nano Pants
Purchased these after seeing others wearing them on a recent trip. They are lightweight and warm, and perfect for the traveling angler who seeks to minimize weight while traveling by air and having a versatile garment on arrival. Overall I am very pleased with this pant.

Worth the money, excellent puffy pants
I bought these for backpacking to wear at night while sitting around before sleeping and in the morning. It will be awhile before I get to test them for that but I’ve worn them on my morning coffee shop walks, high 30’s (F). First time with mid weight thermals and rain pants and was melting. Takes about 30 min there and back, easy walk. Second time left out the rain pants and still to hot. Third time just the puffy pants and still to warm but okay. This coming Sunday morning should be 30 degrees and I’ll sit outside drinking coffee, maybe just mid weight thermals and I think they’ll keep me warm. I’m going for not wanting to know it’s cold at all while doing nothing. They will be great! If you are doing any sort of light activity they will likely keep you warm down in the teens with thermals. They are more baggy than what I want but I’m not very big, 5’ 10”, 160 lbs, 31” waist. I bought mediums and would probably be better off with a small size but they are not faling down.

Kept me warm in an underrated bag
Bought these for winter camping while ski touring and they were excellent. Put them on immediately after touring and they kept me warm and cozy. Stayed warm all night in very cold conditions with my under rated sleeping bag. They literally saved me. I'm 6'2" 170 pounds; large are too big.

Very warm
I got these pants as a gift for my son to wear under his dry suit on a Grand Canyon rafting trip in December. The fit very well and do not ride up on the legs as other reviews have said. He is very happy with them and likes them a lot.

Durable, packable insulating pants
I bought these for my father in law after we both own the Nano Puff jackets. They fit perfectly and have durable backing at stress points (seat and knee). Hard to go wrong with this lightweight, packable insulation that performs when wet and drys quickly. Wish Patagonia made them in a longer inseam for taller individuals.
