Reviews Summary
Customers say these biker shorts are extremely comfortable, soft, and stay in place without riding up. Many reviews mention their excellent performance during workouts, long work days, and active pursuits. The breathable material moves well with the body and doesn't require constant adjusting. Some note the waistband can loosen throughout the day.

    Great design in FLEX!

    I wear the Biker Flex a LOT, and having new designs added is a great day! I wear these under hiking shorts and pants to prevent chafing, then, at base camp or at home, I wear the ultra soft modal Ballers.
