Closing the Gap: Nite Ize TRU Zip Waterproof Zipper Is Revolutionary

The TRU Zip waterproof zipper by Nite Ize is a patented technology taking the outdoor industry by storm.

Based in Boulder, Colo., Nite Ize is already known for pushing the boundaries in outdoor lighting products and other useful everyday products. The silent, self-contained TRU Zip waterproof zipper is the latest innovation in a long line of emerging products from the 30-year-old company.

Each inevitably leaves us with one question: Why didn’t someone think of this before?

Waterproof TRU Zip Technology: How It Works

Nite Ize’s new TRU Zip technology is yet another smart solution for gear that needs to wear without a tear. There are other waterproof bags and existing seam-sealing mechanisms. But TRU Zip is the first of its kind: a pull-slider zipper with a fully closed assembly.

The technology, which comes in 4mm and 6mm widths, creates a toothless, snagproof, waterproof seal like nothing else on the market today. GearJunkie recently gave TRU Zip a Best In Show award at the Outdoor Retailer Snow Show.

You can submerge a TRU Zip-sealed bag in fresh or salt water, drench it in rain, or soak it in melting snow. An IP67 rating means the futuristic zipper is both submersible up to 1 meter for a maximum 30 minutes and fully “dustproof.”

Nothing is getting through or sticking to this watertight cincher. TRU Zip can also be radio-frequency (aka “high-frequency”) welded in ways that were never possible in the past, making it functional in an array of applications, even outside the Nite Ize brand.

TRU Zip glides silently and smoothly from a self-contained, overmolded “garage” at one end of the zipper and locks into place at the other end. Using TRU Zip is like a “satisfying” YouTube video. If you’ve ever watched someone playing in kinetic sand or slowly spreading frosting, you know what we mean. This zipper is kind of magic. And you’ll want to pull it over and over to see how it works.
