SILVERAIR MERINO WOOL BOXER-BRIEF [2.0]

A high performance boxer-brief made with luxurious 17.5 micron merino wool and real silver. Our custom double knit fabric weighs 200gsm and has a terry finish on the inside that is incredibly comfortable and a dream to wear. The silver neutralizes odor causing bacteria and takes the natural anti odor performance of merino to the next level. A silicone grip system prevents the legs from riding up or bunching. The 2.0 version now features a gusset reinforced with nylon that is more durable against abrasion.

FIT GUARANTEE

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.

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.

SilverAir Sock

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.

Friends totally likes them

Purchased for a gift for a friend who travels a great deal. He thinks they fit great, likes wearing them also at gym and had compliments on how he looked in them there.
