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.

Great Underware. Got them in my monthly birchbox, but I can not see paying $31 a pair for them so I will stick to my Calvin Kliens.5
These are likely the most comfortable briefs I've ever worn. They're a little too pricey for me to purchase additional pairs, but I would if I could. Highly recommend.4
Good for working out in. Comfortable and nice material.4
prior to receiving the birch box i had never heard of this brand. really functional design, great materials and quality craftsmanship! my wife even loves the look! think about that fashionable underwear! A serious addition to my preferred brands list. Will definitely be purchasing more.5
These are fantastic for working out or a job that you may sweat a bit. Don't ride up and allows for breathing but definitely pricey. Can't buy as many as I'd like but they're good.4
the fabric is just right. the styling and fit are perfect.5
Great fit comfortable and good ventilation but way out of my price range thanks for the sample pair I will cherish it!5
super comfortable. lighter than under armour and it feels like its not even there!5
I think the fabric is soft and breathable but bircbox sent me a large and I need a medium.5
I wasn't expecting to get something like this in my box, but I like some of the features and expect it to work well for exercise.4
