Every Catalyst AirPod case is tested for waterproofness according to IP-67 (up to 1 meter deep). Take your AirPods with you while jogging, swimming, hiking, climbing, skiing, fishing, camping, and more. The Catalyst AirPod case exceeds the military standard MIL-STD 810G for shock and drop protection from heights of up to 2 meters. The case is made from shock-absorbing polycarbonate and features a silicone cover. Rain, water, snow, dirt, seawater, and dust – your AirPods are protected against these elements when using the Catalyst AirPod case. The detachable carabiner makes the Catalyst case more accessible for your AirPods and helps prevent loss and theft. The Catalyst AirPod case is made from high-quality silicone. Other cases are made from simple silicone and can become defective after a short time due to tearing or breaking. The smart design allows for easy and straightforward access to the Lightning port.
