These hardly came off my body for two weeks in Iceland in April. Worn as a base layer under hiking and rain pants, or under just the wind breakers. Great odor control after a week of not showering. They snapped back into shape after washing, so no baggy knees. Great investment, will get more next season.
I thru-hiked the Pacific Crest Trail with these long underwear for 5 1/2 months. They were awesome. Super warm and comfortable on cool nights on the trail. I also use these for skiing all winter long. I love them! I definitely recommend them to everyone.
