Essential Bikini

Our Essential Bikini is designed to stay put and move with you, while keeping you funk-free, dry, and comfortable throughout your entire day no matter your adventure. Crafted from super-fine Merino wool, our seamless design and comfort waistband eliminate digging and rolling during your hike, ride, climb, workout, or vinyasa — so comfortable, you’ll forget you’re even wearing it!

Bonus: Our ZQ, OEKO-TEX, and Responsible Wool Standard certified Merino is also regenerative and sustainable. (which also means it is free of BPA, BHP, and toxic forever chemicals).

Double Bonus: Our Bikini is great in and around the water. It dries in the blink of an eye.
