Why did we spend a year and a half on underwear?

Because underwear is easy to make. Good underwear, apparently, isn’t. We went through dozens of fabric and pouch revisions, three waistband redesigns, and a six-month wear test before we were willing to sell this pair. Every version fixed one thing and usually broke another, until this one didn’t.

See the full test

Most boxers start good and get worse.

They start soft. Then the legs creep up. The waistband folds. The pouch either squeezes everything flat or gives no support at all. And a few washes later, they don’t feel like the pair you bought. We got tired of it. So we spent eighteen months trying to fix all of it in one pair, instead of launching ten average ones.

The Boxer Brief

One boxer. Six things we cared too much about.

You wear boxer briefs more than almost anything else you own. We thought that was a good enough reason to get obsessive about the details.

The stand out

Before launch, we gave KLOON to an independent tester and told him to actually use them: six months of wear, twenty normal washes at 40°C, and two completely unnecessary 90°C stress washes. The fabric, shape and waistband held up. He also told us what he didn’t like. We kept that part too.

Wear them. Wash them. Decide.

Underwear is difficult to judge from a product page. So don’t. Try KLOON for 30 days. Wear them. Wash them. Live in them.

If they’re not for you, send them back and we’ll refund you.
