    Measurement Guide


17.5 Micron Ultrafine Merino Wool. No Compromises.

For the base fabric of this underwear, we sourced ultra fine New Zealand merino wool for it's natural ability to regulate temperature and resist odor. A hint of spandex is added so the underwear does not lose it's shape and a double soft premium waistband feels like a cloud on the skin and won't leave any marks.

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


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.

Sceptical but oh my God they work!

I travel, a lot, and the biggest thing is long plane journeys and then meetings. So these looked like a very good idea. But I was sceptical. I wash underwear daily, these can't be any different. How wrong I was! No smell no sweat and Oh do comfortable! In fact they worked so good I actually tested to see how many days I could wear without washing. Whilst not all day I finally washed on day 6... But more out of habit they still didn't smell! So bought another 3 pairs which I am leaving to replace others as they wear out. If in doubt... Buy... You won't regret it!

Comfortable wear, great for outdoors

The underwear is thicker than I thought but very comfortable to wear. It has been odor-free after sweating quite a lot except it can resist the smell of urine after a few days. I intentionally worn it for a few days before washing, while I did quite a lot of walking, some biking. Its result is quite satisfying compared to other brands Merino wool boxer that I had, in terms of the smell and comfort level. A few suggestions though. There ought to be a opening in the front so that I don't have to pull down every time I go to toilet, as the elastic waist band is getting a little bit loose after these few days. The drying rate of the underwear is also slow especially when compared to others, it is reasonable for its thickness but faster is always better.

I have purchased both the boxer brief (7 pair) and the t-shirt (long and short sleeve). I can say - without a doubt - that these are the best underwear on the market. I searched high and low . . . and found the BEST!

Actually very smooth and comfortable

I didn't think they were that comfy at first. I got only two pairs and every time when they're in laundry and I'm wearing my usual ones I really miss the new ones - so much more comfortable! The only thing is that they are so expensive when I think of me spending so much money on boxer shorts it kind of hurts, i mean man those are just boxer shorts maybe i have to find some other comfy-like boxer briefs.
