The edges roll up during intense activity, seams rub your skin raw, and poor moisture absorption leaves you sweaty and itchy.

Constantly pulling down your underwear mid-run is embarrassing and distracting, and painful chafing can ruin your entire training session.

We added anti-roll silicone tape on the leg openings, flat-lock four-point six-stitch seams that eliminate friction, and silver-ion moisture-wicking technology that keeps you dry.

Q: How do the flat-lock seams prevent chafing during long runs?
A: The flat-lock seams lay completely flat against your skin, with no raised edges to rub and irritate, giving you a completely chafe-free experience even during marathon training sessions.

Q: How well do the anti-roll edges stay in place during intense movement?
A: The premium silicone grip tape locks the leg openings in place, so they never roll up or shift, no matter how intense your workout gets.
