best underwear ever
the most comfortable underwear ive ever had!!! really good for sport and other activities where you need quality underwear. About sizing- its true-to-size.

These are great boxers
I had tried Patagonia Active Classic (too loose/no support but good for low activity wear) and Active Sport Boxer Briefs (nice, but very supportive and better for intense activity) and was looking for a boxer for everyday, but active, use. These fill the bill perfectly, with a comfortable, supportive fit between the other two Patagonia synthetic boxer offerings referenced above. The material breathes very well, dries quickly and is very comfortable next to the skin. I have used them on long hikes with no chafing and just the right trade-off of support and comfort. They excel in everyday wear, as well. They look great. I will definitely be buying more of these boxers! I am 5'11", 175 lbs. and the Mediums fit nicely.

Cap 1 Boxer Briefs
This item was a pleasant surprise having a very comfortable waist band and the smooth filling of silk against the skin.I will purchase more and will never buy cotton briefs again.Some men may need to order one size up.

silky smooth and cool
I've had this model in this fabric for several months so I can write about fit and comfort. Both are excellent especially after hard exercise when you're looking to cool down and dry off hours before you can hit the shower. I mean, for a lot of us this is why we're wearing these things, right? These surpass the other Patagonia weight and other brands too. Stretches where it's supposed to and never binds or loosens up where it isn't supposed to. The durability seems very good but it has only been a few months. I am very glad to purchase more of these guys. The variety of patterns makes that easy too.

Very Comfortable
These are great underwear for everyday use. Since they wick moisture, they can also be worn as athletic underwear for outdoor activities. I am very pleased with my purchase and will continue to buy more Patagonia underwear. Fit seems standard/normal.
