D30 armour is the world's number one impact protection brand and are available in limb and back protectors. D30 uses highly guarded intelligent molecule technology which lock together on impact. This causes the soft malleable armour to harden and stiffen on impact giving much greater protection than other protectors on the market. The technology in D30 armour enables the protectors to be manufactured with a much lighter and smaller profile than other armour so you won't end up looking like the Michelin Man! This makes jackets lighter and more comfortable to wear without compromising on safety and protection.
