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 was happy to get these after watching the sneak peek video. Soft and moves with me.4
My boyfriend got these in his birchbox and loves them. They are incredibly soft and comfortable. Would definitely purchase them.5
They are a little short. Closer to a trunk cut than a boxer brief cut. Comfortable, though.4
Great quality and feel while I was working out, but the are really pricey.4
My favorite park of these boxer briefs is that they have a built-in pocket! I mean how cool is that?! Other than that they are extremely soft which is feels really nice on the bum and the you-know-what. They are a bit pricey but overall they are great to have!5
I like how light and flexible the fabric is, but I like a little more support.3
Great underwear is weirdly satisfying. Its like great socks. No one needs to know they're great but you.5
I'm never buying a pair of Hanes again. These underwear are worth the ridiculous price for the comfort. I've never felt so comfortable. I am going to buy more.5
I got these as a sample in my Birchbox, but they were the wrong size. I am going to order a pair soon because the ones I have currently are amazing. I just wish I would have updated my profile after I lost weight.4
As someone who has to constantly hide their apt key and/or safety pin it to my boxer briefs, these are a particularly appropriate gift. Comfortable, sweat-wicking, and form-fitting. I've yet to try the horizontal port. Glad to see Birchbox hit one out of the park. A bit pricey for briefs, but worth owning a couple pairs for runs and races assuming the quality holds up over time.5
