How to preserve it for much longer?
Hand wash to preserve the bamboo softness for longer. Avoid bleach, fabric softener and harsh products. Air dry in the shade to keep the fit and stretch intact.
Forget about underwear that rides up, feels tight, or gets uncomfortable throughout the day.
It moves with you, so you can focus on what matters most.
Made to keep up with your longest days.
Less of that damp underwear feeling after the gym, a run, or a hot day.
The difference starts after a few hours.
Cotton fades with time. Bamboo-rich fabric keeps its softness, lightness, and clean comfort from morning to night.
Underwear sits in one of the warmest areas of the body. K.O.'s bamboo-enriched fabric is lighter and more breathable, helping you stay cooler all day long.
No. Polyester is plastic-based and can feel synthetic on sensitive skin. Cotton is natural, but can feel warmer and heavier. K.O.’s bamboo-rich fabric feels softer, cooler, cleaner, and more premium through the day.
Regular cotton feels familiar. The difference starts after a few hours.
Simple: we'll exchange it. We don't sell risky purchases—we sell confidence. If it doesn't fit, you have 14 days to exchange or return it, no fine print and no hassle, as long as it complies with our Exchange & Refund Policy.

That's the promise behind the K.O CLUB name: Built to Move With You—Not Against You. The ergonomic fit and stretch fabric are designed to move with your body all day long—no riding up, no readjusting, and none of the discomfort you'd expect from ordinary underwear.
Bamboo fibre is different from polyester. Polyester can feel synthetic, warm and sticky when heat builds up. K.O's bamboo-rich fabric was chosen to feel softer, cooler and more breathable against the skin.
