Birchbox Breakdown

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. Don't know your size? Check out our Sizing Guide.

How it Works

360° stretch technology moves with your body to prevent riding and chafing, while microfibers absorb moisture and odor for enduring comfort. A convenient horizontal fly facilitates calls of nature, and a utility pocket stores cash and cards when you’re wearing those pesky, pocket-free gym shorts.

How to Use

While these tricked-out trunks were designed as activewear, breathable fabric makes them a welcome addition to your daily underwear roster. After all, lightweight linen pants are only as comfy as the briefs they cover.

Great

I use it all the time. Very comfortable! It can be use anywhere and anytime so you don't have to think about it. Most of the time you don't even know you have it on.

Favorite briefs
Purchased

I was worried at first by the size (the box came with an XL and I normally buy a L), but they fit perfectly. They are so comfortable that my gf ordered me an extra pair for Valentines Day.

Really surprised

I was really surprised by this item. In a good way. Breathable and comfortable whether working out or wearing with jeans. Love the Ipod pocket for working out!

Perfect workout trunks

Love these for running and working out. I was sent a large in my box and didn't think they would fit due to the sizing chart(size says I should have a medium), but they fit well.

Good one

Hubby liked it very much and even told me to be careful not to damage when removing the tag. The fit and material was good. He'll buy more definitely.

Quickly becoming my favorite pair

I used to be boxer man and I was looking to make a change in life to get some more support. These came at the right time and now I'm slowly replacing my whole underwear collection.

Amazing!

These are truly amazing, they are super soft and stay in place. I first thought I would feel whatever was in the pocket and they wouldn't work out. However you don't feel what is in the pocket at all!

Love these

So happy to receive these in my box a few months back. They are extremely comfortable, nice elastic, nice fit. Haven't used the card/key pouch yet but see how it could be useful. Definitely recommend.

Athletic fit

I wrestled in college. I like the tight fit of my boxer briefs. I continue to wear the microfabric spandex type briefs of the large corporations. Tommy John did it right. These sport trunks are my favorite pair of undies. They are long enough as to not chafe my inner thighs, as some of the briefs I have gone through did. I would wear them every day if I had enough of them! Thank you for putting this product on the market!
