Star Flex Shapeshift
The 3" active boxer brief for maximum range of motion. Star Flex's short inseam stays out of the way during yoga, pilates, and studio workouts — with sweat-wicking recycled fabric and medium compression that holds its position.

- Sweat-wicking, quick-dry recycled poly — lightweight and fast-drying for studio and cardio use
- Medium compression — holds position during movement without restricting hip flexion
- No elastic digging at inner thigh — leg opening lies flat, no pinching
- Sleek, smooth construction — friction-free under any athletic bottom
- Organic cotton gusset — breathable natural fiber where it matters most
- Zero wedgies during dynamic movement — stays in place through high-knee work
- Size-inclusive — XS to 4XL
