Finally, comfortable active underwear for athletes. Biker Flex is our classic 9” inseam boxer brief in a lightweight, sweat-wicking, and supportive recycled poly fabric.
• Active underwear made for movement • 9" inseam, our longest length • Medium thigh compression • Sweat-wicking and quick-drying active knit fabric • Sleek and smooth for friction-free fit under clothing • Organic cotton gusset for breathability and hygiene
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
