Windproof and waterproof, these matches work even in the worst conditions. They are protected by a rugged watertight case that features deep ridges, making it easy to remove the lid even with wet or cold hands.? Each storm match burns for up to 20 seconds, making it possible to ignite tinder easily. The durable case is watertight (IP67 Rated) and includes two strike pads; one along the body and the other pad under the watertight bottom cap.
