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 Shirt


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.

Best Wool boxer briefs I've tried!

I've had a few pairs from Y athletics for awhile now and they've held up great. The merino and silver air really work at reducing odors allowing to wear even multiple days and feel fine. The grip on the legs is a must for me to prevent them from riding up. They are a little too thick/warm for summer months, but during cooler weather and winter they are my go to.

Best for Comfort and Cleanliness

Great for travel. You can wear it for a week at a time. It can be easily washed and dried. I have been wearing them for a couple of years now.
