Redesigned for 2009, the Synergy ST4 shoulder pads offer plenty of protection for physical games. A floating sternum chest plate and Spine Tec spine plate protect the critical impact areas and disperse energy away from those areas. SHOX technology combines different densities of foams to disperse impact. Segmented rib wrapping contours to the body and protects the rib cage from impacts. The low profile shoulder caps provide maximum protection while still allowing excellent mobility. The segmented chest pieces increase range of movement without sacrificing protection.
