The products from the Seal-D series are the ideal companion for a variety of leisure activities. Made from 100% waterproof and ultra-durable PVC material, the contents are safely protected from dust and water. All seams are welded to be waterproof, and special splash-proof zippers are used to ensure tightness. To securely close the Seal-D pack bag and backpack, simply roll the closure 3-4 times and then secure it with the nylon buckle. The travel bag can be closed with a splash-proof zipper. The flap covers the zipper for added protection against splashes. Tip: Before closing, compress the contents by applying light pressure from the outside to release unnecessary air, allowing the bag to take up less space. The Seal-D products are tough and durable. Robust rip-stop material and sturdy seams ensure a long lifespan. Whether on your next outdoor, camping, or boating trip, they are your go-to choice whenever items need to be stored safely and securely.
