95% TENCEL™ Modal fibers, 5% elastane, in a lightweight 170 g/m² jersey. Machine wash on 40°C (104°F) with like colors on a gentle cycle, and skip the dryer.
KLOON is true to size, but runs larger through the body and legs than most underwear on the market. Many men size up a notch for room around the groin — with KLOON’s 3D pouch, that’s not necessary. The fit also holds up wash after wash, unlike a lot of traditional underwear that loses its shape. For an average build, M is usually enough room. For reference: at 186 cm (6′1″) and a 92 cm (36″) waist, I’ve worn L my whole life — with KLOON, I wear M.

The fabric
95% TENCEL™ Modal fibers, knitted into a lightweight 170 g/m² jersey. The fibers absorb and release moisture, supporting a naturally dry feel from the first meeting to the last train home. A 3D pouch gives support without compression — and the softness lasts, wash after wash.
Nothing decorative. Every choice in this pair exists because it changes how the day feels.

Finally, boxers that don’t ride up. I’ve already ordered six more pairs.

I was skeptical at the price. After twenty washes, they still feel new.

The test
Office days, commutes, training — and 20 full wash cycles. We tested KLOON against the boxers you already own, and ours held their fit better than every pair we compared. That is why the guarantee is 30 days, not 14.
We are confident these are the best boxer briefs you have owned. So every order carries a 30-day fit guarantee.
Not convinced? Send them back — even after wear and washing — and you get a full refund. We pay the return shipping.
The legs are designed to stay put — balanced elastic, the right inseam and fabric with real recovery. In our six-month wear test, reduced ride-up was one of the clearest results.
The size you normally wear, from S to XXL. The shape comes from the 3D pouch and the fabric, not from tightness. Between sizes? Take the larger one.
Machine wash on 40°C (104°F) with like colors on a gentle cycle, and skip the dryer. That’s how the softness lasted 20 washes in our test.
You have 30 days — our risk, not yours. Full refund, even after wear and washing, and we pay the return shipping.
