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, functional. Unfortunately too expensive, but a great product.5
These are really soft and smooth, which is the most important when dealing with underwear! The pocket also makes these great because it fits an iPhone if you are at the gym, or other more personal items out of sight. Will buy more, just wish they had multi packs to get the price down a bit.5
I really liked the feel of the Sport Trunk material but I am more of a brief guy!4
Love the weiner hole, the different design is also very neat.5
Very soft and breathable make these a very comfortable fit. And that's where I run out of compliments. The pocket isn't something that seems very useful, as keys are too bulky (plus pockets have remedied this). My only gripe is the price. I would never pay $30 for a pair of underwear. My normal $15 for 3 pairs briefs do me well enough. Thanks for them though Birchbox!3
love these, nice comfortable fabric, and even has a little pocket.5
Great product. I always buy cheap boxer briefs and these were a welcome surprise. Great quality and fit, would buy these in the future.5
Needed to size down for these, the XL is huge. Luckily Birchbox was super helpful with providing a replacement product!5
The underwear is very light and comfortable. The price is a little too much for my taste.3
Overall these are super comfy and I was impressed with them. I'm not a trunks guy, but they worked well and didn't ride up (which is crucial). The horizontal flap is a bit disconcerting at first but I've gotten used to it.
The only thing I think is gimmiky is the pocket. 99% of all men's pants include pockets so do you really need a pocket there?
