A high performance boxer-brief made with luxurious merino wool and fused with our SilverAir anti-odor technology. A silicone grip system prevents the legs from riding up or bunching. Perfect for travel but so comfortable you'll want to wear them every day.
We want you to love your gear and offer a try-on guarantee for your first pair of underwear. If you don't love it, let us know within 30 days of purchase and we'll send you a different size or take it back and issue a full refund.
For the base fabric of this underwear, we sourced ultra fine 17.5 Micron New Zealand Merino Wool for it's natural ability to regulate temperature and resist odor, while having a buttery soft hand feel that is dry to the touch. SilverAir metallic yarns neutralize bacteria and reinforce odor-control. Finally, a hint of spandex is added so the underwear does not lose it's shape over time. The waistband is constructed with a double-soft nylon that feels like a cloud on the skin and will not leave any marks.
Merino wool is naturally resistant to odor-causing bacteria, but silver actively neutralizes any bacteria it comes into contact with. That's why we infuse our SilverAir technology into the underwear to give it the best possible anti-odor performance in the market.
Inspired by grip systems in high-end cycling apparel, we designed a custom grip using soft silicones that you barely feel against your skin but which creates just enough resistance for the leg band to stay in place.
I'm always on the lookout for a better pair of underwear. I've been wearing ExOfficio stuff for a while now, and despite backing numerous Kickstarters and other outlets I've not been able to find anything comparable. Then I received my YAthletics Flyless Boxer Brief. I'm wearing it for work, for athletics, and just sitting around the house. After a few weeks, they've become my favorite underwear by a longshot. I'm on here to order more! The length of the brief is right for me, and the adhesive helps keep them from rolling up most of the time (better than basically every other pair I've tried). The material is soft but has a sturdy feel to it. It dries quickly, and it does a good job of absorbing a little sweat without feeling like it weighs 20lbs. I do feel compelled to mention the sizing due to a remark from another reviewer. He said that he recommended sizing down. That's completely the opposite of my experience. In almost every brand I go with a Large, but I found the XL to be a perfect fit here.
Ok, so I didn't like the brief version, and contacted them for a return. I got a response and refunded within 10 minutes, maybe less. So - that's impressive. I will try the style with the 8" inseam, as I think they may better suit me and compare to the underwear I use now. I will say the material felt comfortable, just too short for me. I hope I like the next pair. On the pair I had, the top tended to roll down, but I was just informed that they made a design change that will fix that on my next pair.
I was a Kickstarter backer of this underwear. My husband absolutely loves them. He loves them so very much that, as fiscally conservative as he is, he asked me to get him more, since the first batch is wearing out (he is exceptionally hard on clothes). So I have ordered 12 more pair. Significant investment, absolutely - especially on our budget. BUT these are so very much significantly more comfortable that he is willing to spend the money. Terrific customer service before and I'm sure it will be again! And he will be so glad that they now come in XXL - they should be absolutely perfect. Definitely worth the cost. If the new shirts, now being introduced through Kickstarter, had a front pocket, I would get him some of those as well. He will only wear shirts (and t-shirts) with a front pocket.
Great underwear. Comfortable and fit is great. Looks good (according to the wife!). Ordered to deliver at my hotel, worn over three days with no odour or loss of fit whilst on business trip. Merino breathability excellent! As a long standing Icebreaker customer I think this is a big contender to switch!
a leg length slightly shorter then the long boxer brief and slightly longer than the regular size would be amazing.
