Bamboo Viscose Underwear
FAQ
Why should I switch to bamboo underwear? My cotton undies are surely good enough
No - cotton undies aren't good! Our men’s underwear and women’s underwear are made from viscose derived from bamboo - a fabric that’s breathable, super soft, moisture-wicking, and surprisingly durable. Oh, and it’s environmentally friendly too.
How do I choose the right size undies?
Finding the right fit is easy. Just head to our size guide for all the details. If you’re between sizes, we suggest sizing up for extra comfort. You can also browse our men’s underwear or women’s underwear collections to see how each style fits before you choose.
Is there a guarantee if I don't love them?
Yes, we’ve got you covered with our First Pair Guarantee. If you don’t love your first pair, we’ll refund you - no questions asked.
