They regulate body heat perfectly and wick away moisture. You can wear them for days with no stink, and they never ride up. They are super soft, true to size, and have the perfect amount of support. The only annoyance I have is the tags on the waistband are a little rough.
These keep you relatively warm. They seem to wick alright, but not as well as my merino wool boxers. The fit is a little off. The waist is a bit loose and the leg openings are a little small. They might work better for someone who does not have muscular thighs and butt.
These are warm and comfortable. Overall, they are great and don't smell. However, I wish the fit did not ride as high up as it does. Also, the waistband is a little thick. I like very thin, flat waistbands.
