The 4.5 Lite jacket is water-resistant, breathable, lightweight and made of a four-way stretch softshell material with large, zippered ventilation and removable arms to keep you cool even on the hottest days. The abrasion and cut resistant brush guard protective film reinforce an already durable elbow and shoulder panel made of 1000D nylon. The tailored waist-length fit is designed to work with or without body armor, and the collar can accommodate a Leatt neck brace if worn.
