UnderFlex Compression Boxer Briefs for Men: UPF 50 Built into Fabric.

These are pretty fantastic. Light, breathable, comfortable, absolutely everything you'd expect in a pair of performance underwear. They fit well but do not go as far down the leg (I'm 6'1") as the pictures seem to indicate. That's not at all a problem for me as I prefer them the way they actually fit. I bought one pair to try out as something to wear under unlined board shorts and after wearing them for a while I immediately ordered several additional pairs.

The description said that these were good for wearing under boardshorts, implying that they were quick dry, which is why I got them. It turns out, they retain water like crazy. After rinsing them, wringing them out, and hanging them to dry overnight, they were still soaked when I felt them the next morning. Very comfortable, though.

I really like these. They feel very comfortable on and do not bunch up when moving around. I'm taking one star off because the crotch area seems a little small, and that's with a medium when I normally wear a small (went up a size based on some reviews). I would like to see them make some yoga shorts for men of this quality with a bit more padding in the front for discretion to wear without shorts.

Not the widest band. Baleaf is. Similar quality, with one major exception. This product has a narrower waistband, and will curl up.

I've got to say, I'm hard on my underwear. I hate holy underwear and my lifestyle demands the most from my hidden garments. I wear these guys all day and never adjust. I wear them to work and to the gym and they are the best boxer briefs I've ever owned. They are perfectly supportive and extremely comfortable. No pretense, nothing too commercial and a fantastic fit. I would recommend them to anyone.

Great quality fit well in the legs but they are very tight in the package area and butt.

I am a size 29-31 depending on brand. Based on the reviews, I went ahead and bought a medium rather than the small, and I will say it was definitely the right choice. The mediums are plenty tight. Smalls would have cut me in half. ORDER A SIZE UP.Otherwise, they seem to be pretty functional. I wore them under board shorts and they work pretty well.

I purchased 3 of these boxers, one in each color. They fit as expected (size Small) and are very comfortable. The composition is a perfect blend that provides a soft material that is flexible, yet has enough compression to comfortably hug your glutes and upper hamstrings. I prefer these over Under Armour's Boxerjock, which is looser on the glutes and tends to ride up more. Looking forward to trying YogaRat's other products.
