The MTB Crash Pant A delivers maximum protection in a bulk-free short. The shortâÂÂs thigh, hip and tailbone pads are all removable and made from form-fitting, soft-shell ACF foam, which absorbs 95% of impact energy for a safer, more comfortable fit. The shorts also include a Coolmax chamois crotch gusset, to minimise chaffing, add comfort and ventilation and guarantee longer lasting freshness where it counts.
