LIGHTWEIGHT AND WATER RESISTANT 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. If you are looking for something waterproof take a look at the all new 4.5 Hydradri, or if you need to accommodate more storage and a hydration bladder take a look at the 5.5 Enduro Jacket, or something super vented the 4.5 X-Flow.
