MATERIAL

17.5 Micron Ultrafine Merino Wool. No Compromises.

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.

SILVERAIR TECHNOLOGY

Taking odor control to a whole new level.

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.

SMARTGRIP™

A grip system that prevents ride-up

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.

Close to perfect

I've tried pretty much every high end brand of men's underwear and these are some of the best. The Merino is super soft and the fit is overall very comfortable and at the same time supportive. I even wore them for 5 days in a row, which sounds gross, but I wanted to stress test them. they didn't smell at all after five days and I wash them just for my own peace of mind. I ordered a medium which is my normal size and pretty much everything and is generally a little bit roomy me if anything. the medium fit okay in the waist and legs what was quite compressive,especially in the crotch area. the customer service representative sent me a large without any questions asked and it fits very well. Great company and great products. I hope that they last a long time since it is a high price point

Quickly became my favorite underwear

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.

Greatly Improved

I've been rocking the Silver Air Boxer Briefs since the Kickstarter, and they're easily the best. The horizontal fly is brilliant. The grippy stuff on the legs is fantastic. The fabric is fantastic. However, this most recent iteration with the gusseted crotch (and the two-tone fabric in the case of the Grey pair) is an incredible improvement. The crotch had started to wear out on some of my first pairs, but the stress reduction on the fabric from this new construction is amazing. Well done! Please apply that to all the boxerbriefs!

Favorite Rock Climbing Boxers

These are my go-to boxers to climb in now, they never smell bad which is incredible. They keep me warm during cold outdoor boulder session in the North East and keep me cool during indoor sessions at the rock gym. I hang them up between uses to let them air out and they last much longer than I’d like to admit between washes but even my girlfriend can’t smell anything on them after I’ve had several climbing sessions. 10/10 recommend. I’d get more if I needed, but I don’t think I’ll ever need boxers again.

Perfect pair

I still have a pair of V1s and they are great. The very few changes I wish they would have made, they did. These are simply great underwear and worth every penny.
