Long Bamboo Anti-Chafing Shorts with Built-In Underwear

Our 2-in-1 Bamboo Anti-Chafing Shorts come with a built-in gusset, eliminating the need for a separate pair of underwear. No more tight, uncomfortable layering, just one premium piece of underwear that protects your thighs from chafing while keeping you cool and confident all day. Crafted from super-soft bamboo viscose, these shorts wick away moisture, regulate temperature, and reduce irritation on sensitive skin. The extended leg length sits just above the knee to guard against friction, and inclusive sizing (UK 8–30) ensures a perfect fit for every body. Step out in skirts, dresses, or gym gear without the worry of thigh rub or bunching.

For our long anti-chafing shorts we use Tanboocel bamboo viscose fabric that is manufactured in a closed loop process meaning that excess water and gas is recycled.

The key factor is that Tanboocel bamboo viscose does not use carbon-disulfide (which you should avoid) in the extraction process and alkali used for processing bamboo chips is recycled.

We use plastic-free corn starch packaging that is 100% compostable and disposable.
