Essential Thong

Our Essential Thong has a "forget it's even on" level of comfort and a low profile. Crafted with the finest Merino wool, it will keep you funk-free, fresh, and dry all day long. Our seamless design and comfort waistband eliminates digging and rolling during your hike, ride, climb, workout, or vinyasa. It’s the perfect “barely there” solution for your toughest workouts and longest adventures!

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: Virtually invisible under leggings and base layers, our Essential Thong feels like a second skin and stays put as you bend, squat, and stretch.
