GBA4- A VERSATILE TRANSFORMING BACK ARMOR / Back protector

GBA4 is a one-of-a-kind harness device that offers full back protection armor for skiing and snowboarding. Thanks to its proprietary Dynamic Hinge and detachable Core, GBA4 can be folded in half and carried or stowed with ease while traveling. GBA4 also features the Core Switch Technology; instead of replacing the whole pad to upgrade its performance level, you can simply switch the Core to freely shift between EN1621-2 Level 1 and Level 2 depending on the terrain and challenge level.
