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.

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.

Love em!

They fit great and are super comfortable. The fly is a great addition. I bought the first generation of them that didn’t have a fly and like these better. I ordered the 8” long ones for winter, hopefully you’ll make those with a fly soon.

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!

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

Best of the Best

I can't speak highly enough about this underwear. After comparing the Y Athletics SilverAir Merino Wool Boxer Brief against 5+ alternative brands over the course of more than a year, all others have been officially purged from my wardrobe + replaced entirely with Y Athletics. It's rare for a brand to stand out so conspicuously from its competitors, but this underwear trumps all others in every category, including: Fit, Feel, Design, Technology, Durability, and Value. 10 Stars for this product. Buy with CONFIDENCE.

Great underwear

The fit and feel of these is perfect. I was a little worried about sizing. I normally wear Calvin Klein stretch boxer briefs in a small, but going by waist size I decided to order the SilverAir boxer briefs in a medium and it was the right choice. They feel great, bunching is not as bad as other underwear. I had a chance to wash them and they came out of the laundry in great condition. I definitely plan to order more pairs.
