The GripGrab AquaRepel 2 waterproof arm warmers provide next-level weather protection for your arms. The front inserts are made of a three-layer construction: with a 100% waterproof, windproof and breathable membrane - to protect your arms from bad weather. The protective three-layer fabric has a four-way stretch profile - for a close and comfortable fit. The fit is further enhanced by anatomically shaped seams at the elbows and an elastic silicone gripper at the top hem - to keep everything securely in place, no matter how hard you ride. A soft fleece material is used on the back of the arm warmers for maximum flexibility and added insulation. All fabrics have been treated with a PFC-free DWR (Durable Water Repellent) coating, so they effectively repel light rain and splashing water. Protective, flexible and fit like a second skin. Version 2.0 of the GripGrab AquaRepel arm warmers has been fully optimized to provide exceptional comfort even in the worst weather conditions.
