■ Color: Red ■ Stock: 7 【Product Description】 4-layer structure? Windproof and heat retention up. The primary purpose of using motorcycle handlebar covers is to protect against the cold. offeree's handlebar warmers use neoprene, a material that doesn't allow drafts to pass through. Neoprene was originally used in wetsuits and provides high waterproof and windproof performance, protecting hands from rain, snow, and cold winds. Also, high-grade waterproof rubber is applied to enhance the waterproof performance. The fabric itself is designed to be windproof, with a structure that prevents drafts from entering from the grips and levers. The entrance for hands is made of ribbed material instead of being open, which improves windproof performance. The ones with boa on the back retain heat because the boa stores an air layer, making it a design with excellent heat retention.
