Tested to IP67, this high-performance zipper protects from sand and dust, and is completely waterproof submerged in a meter of water for up to 30 minutes. Designed for ultimate reliability and ease-of-use, the extruded TPU system combines mechanical and vacuum forces to create a powerful, durable seal.

Maintaining the TRU® Zip zipper is simple and will keep it gliding smoothly. To clean, simply rinse the zipper rails with fresh water. For optimal performance, lubricate zipper after cleaning, before prolonged storage, or to improve zipper performance. Distribute liquid zipper lubricant along all zipper surfaces, then slide zipper multiple times. Wipe away any excess lubricant with a clean dry cloth and you’re ready to go.
