Say Goodbye to Chafing.
Finer than silk, twice as soft as cotton.
Made with the finest TENCEL™ fibers, our underwear feels silky-smooth with a gentle, second-skin stretch that moves with you. No friction. No irritation. Just effortless comfort—every single day.
Sweat-Proof. Odor-Free.
4x more breathable than cotton.
Tani's fabric wicks away sweat instantly and prevents odor-causing bacteria before it starts. Stay dry, fresh, and confident—no dampness, no smells, no distractions.

Never Adjust Again.
A perfect balance of stretch, support, and softness.
Most underwear rides up, bunches, or shifts, forcing you to constantly pull it back down. We solve this with a high-quality elastane blend for flexible support, precision-stitched leg openings for the perfect amount of stretch, and a no-roll elastic waistband that stays put.

Built to Last.
Long-lasting softness and support.
Underwear takes a beating—frequent washes, daily wear. Our special blend TENCEL™ Modal keeps its softness and shape 90% longer than cotton, so you get lasting comfort without sagging or thinning.
Lower Impact
Made with TENCEL™ derived from sustainably sourced beechwood in a closed-loop process that recycles 95% of resources and uses 20x less water than conventional fibers. Luxurious comfort, lower impact.
