At some point in history—and we’re not sure when—mankind grew accustomed to mediocre underwear. Flimsy cotton and constant chaffing were no longer problems, but simple facts of life. Luckily, these high-performance trunks were designed to break the slump, using microfiber fabric and a host of clever upgrades to keep you dry, supported, and superbly comfortable.

Very comfortable. And sexy style. Almost feels like you don't have anything on.5
The material is nice and comfortable and the design is pretty cool. The fit of the trunks however is all wrong. They dont seem to contour to my body in some areas like normal boxer briefs and trunks do. The other bad part is that they ride very high. Being that I am a younger athletic guy, I tend to not wear my underwear near my bellybutton. This all sounds cray I know but trust me, I havent had this problem before with CK or anyone else, and my body shape is pretty standard. Just overall disapointed2
Probably the best accessory I've gotten from Birchbox yet! Very comfortable and the pocket is a great feature! Can't wait to train in these. Definitely would like to purchase some extra pairs in the future with my BB points!5
Fits well, definitely good for my exercise routine at the gym5
These are great. I already prefer boxer briefs or trunks and these are the best I've used. Especially at the gym. They breath a lot better than any others I've used. Great product!5
I've always used Under Armour products for underwear when I played hockey. I got a pair of these and they are amazing! They are very flexible, while giving support and extreme comfort. A+ product.5
I wish i had a pair for every day of the week! An excellent garment for the gym.5
These support you just the right way when doing any kind of exercise, but are especially great for running. I wish I could afford more pairs of these, but at this price point I can get 3 pairs of similar quality sports boxer briefs elsewhere.5
These boxers are a great fit and extremely comfortable. If they were less expensive I would only wear them.5
I was happy to get these after watching the sneak peek video. Soft and moves with me.4
