Constructed from injected PU for solid colors and a special blend of Nylons and PU for the clear, the V2 Roost Guard is sturdy enough to deflect most debris thrown at it. Adjustable soft shoulder heights is achieved by repositioning the wide woven straps and clips. Comfortable Bio-Foam edging and padding surrounds the V2 and is held in place with our unique PU molded pins. The back features a Poly hinge and allows the plastic to move and follow the body in motion. Soft and flexible TPR panels are sewn in place over the lower chest and back. Multiple large vents holes and an aerodynamic rear 'hump' allow cooling air to flow over, in and through the V2. Side adjustment is achieved by sliding the 'D' ring along the woven Jacquard strap.
