The leggings live up to my high expectations. The cut is well thought out and I find they're the best design for alpha leggings on the market. Love the Lichen grey colour. I'm 5'7", 60kg and the XS fits me well.
love how comfortable they are while active! these are going to be great backcountry sleeping pants, and winter layers
Great pants for my next thru hike adventure
Unbelievably warm for 5 oz, great workmanship and next to skin comfort - truly a game changing piece!
