Like a standard cycling helmet, its composed of a hard-shell plastic outer layer that disperses impact over a large area, while allowing heat and moisture to disperse through spaced vent holes, and a soft EVA foam inner layer, which absorbs and lessens that impact. The two layers, working together as part of a highly flexible, comfortable and breathable pad, will reinforce the front of young ripperslegs while allowing free movement, so that theyll barely notice theyre wearing a guard. Theyll also be able to cinch it round their leg snugly using two adjustable straps. Perfect for giving downhill stars of the future the confidence they need to ride their best, the Youth Rogue Knee/Shin guard comes with its own protective, mesh lined bag that will keep it fresh between sessions.
