Superior protection meets ultimate comfort. The New Ballistic Pro provides the best of both. Air Mesh - Perforated fabric allows air to flow unimpeded, while still providing protection from abrasion and sunlight. Four-Way Stretch - Four-way stretch allows for a degree of stretch in all four directions, providing improved comfort for the user. RMF - Reactive Memory Foam is soft and pliable in its natural state but hardens when force is applied to it, providing a protective barrier. Moisture Wicking - Moisture-wicking material pulls water off the skin allowing you to stay dry and comfortable while riding. Compression fit. Breathable mesh and jersey construction. RMF chest, shoulder, and back protection. Removable shoulder back and elbow guards. Chest meets CE 1621-3 standards. Back meets CE 1621-1 Level 1 protection.
