What Our Gearhead Experts Are Saying:For DH laps and park days, this ReaFlex shirt is a comfort pick—the Level 1 back and shoulder guards stay put but never restrict motion, even when sending big features. The ventilated mesh keeps cool on hot tracks, and that offset zipper is a simple but clutch touch for getting in and out between sessions. Designed for aggressive biking, the Body T-Shirt ReaFlex combines impact-absorbing panels with a breathable mesh build to keep riders protected and cool. Level-one certified back and shoulder guards help cushion crashes without adding stiffness, while the flexible chest pad and ventilated sleeves invite airflow through the whole ride. The offset front zipper means easy layering and quick changes, so whether hitting downhill runs or bike park jumps, comfort comes standard with comprehensive coverage.
