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.

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?
This is an awesome product. Very overpriced for being underwear though.5
These Sport Trunks are comfortable and nice looking. I look forward to trying them out in the summer as I play sports. I'm happy I got one in my Birchbox, because the price seems kind of extreme.5
