Biker Flex Casino
Nine inches of active coverage in sweat-wicking, recycled fabric. The Biker Flex is for women who need full thigh protection during high-movement activity — from pickleball courts to commercial kitchens to endurance runs.
- 9" inseam — full mid-thigh coverage; complete chafe elimination during running and cycling
- Sweat-wicking, quick-dry active fabric — pulls moisture away from skin; dries fast between active sets
- Recycled poly construction — sustainably made; structured for athletic performance
- Medium thigh compression — holds the inseam in place through continuous high-movement activity
- No roll-up — stays at mid-thigh through sprints, lunges, and lateral movements
- Sleek under work pants — smooth enough to wear under restaurant or kitchen uniform pants without bulk
- Organic cotton gusset — breathable natural fiber for all-shift wear
- Size-inclusive — XS to 4XL
