Features

A minimal, brief-style cut with a short 5-inch inseam offers barely-there coverage that disappears under outer layers while allowing free, chafe-free movement

Silicone-free leg hems offer a secure, gentle fit that stays in place without pinching. This design is perfect for riders who want reliable comfort

A wide, high rise waistband gently hugs the core for a smooth, held in feel that flatters and stays put. It sits comfortably above the hips, won’t roll, and adds extra support without squeezing
