The Alpinestars Racer Supermatic Pants are a motocross pant which features many technical upgrades suggested by Alpinestars' sponsored professional riders. Designed to improve comfort and performance the pants have been designed to work with knee braces and there is a new ratchet waist closure with dual adjustment pull-tabs for a safe and secure fit. The pants are made from a poly-fabric/nylon fabric which has been PU coated for additional strength and durability. The seat area is reinforced, and there are leather inner leg panels for superior abrasion and heat resistance. There are mesh panels for ventilation, the legs are pre-curved and the knees have hidden expansion panels designed for knee protectors. There are plenty of stretch panels to improve comfort and fit and there is even an inner hip pocket for keys or loose change. This is quality gear from a brand who prides themselves on their motocross heritage. The Alpinestars Racer pants are ideal for both semi-professional and leisure off-road riders.
