They do what I need them to do.

I wear a 32 (recommended 31-33 for medium). The waistband is loose and there is bunching of material around waistband.

I ordered these with the goal of wearing them on a week-long elk expedition into the backcountry. I had high expectations; temps ranged from high teens to mid 50s, and I was planning on bringing a single pair of underwear that had to do it all. 7 days later, I emerged from the pines with a solid respect for the power of merino. Minimal odor despite many hard miles of sweat-soaked hiking. After day 3 I noticed some pilling on the thighs where my pants rubbed against the fabric, but only time will tell if that matters down the road. The one 'downside'** I would say is that if your sleep system is warm enough to keep you comfortable, these underwear are probably too warm to wear to bed. Next time I'll bring something more lightweight to sleep in and hike in these during the day. **Not actually a downside. These are supposed to be warm.

These boxers are the best. Extremely comfortable, don't ride up, fight odors extremely well, and now with the addition of spandex, hold up better than the red deserts did. Now I just need about 15 more pairs so I can wear them every day.

Much more comfortable and warm than synthetics.
