The “Warrior” technology used in the EVO is based on highly shock absorbing light composite cell materials resulting in innovative lightness, ergonomic flexibility, superior impact absorption and abrasion resistance. Back Warrior EVO is all the above and is also one-size-fits-all thanks to its micrometric height regulation scale on the lower back.The rider simply adjusts the belt on the scale according to his/her height and morphology. Back Warrior Evo is able to fit both male and female riders from 165cm up to 190cm. The belt is also made of punched, elasticized fabric with Velcro and naturally follows the morphology of the user for extra comfort.
