Experiment 133 - Ultrahigh Ziproll

Additional Information

Story

An experimental rolltop backpack with a double-double zipper set up for easy and full access from all sides. Built with the lightweight and super stable Ultrahigh Dyneema Composite fabric.

Fabric

A nonwoven composite of Dyneema brand ultra high molecular weight polyethylene (UHMWPE), the world’s strongest fiber. The Dyneema fiber is bonded and encased in BoPET by Cubic Tech in Mesa Arizona, using their proprietary nonwoven process. The resulting material is sometimes called “Cuben” or CTF3, which we then have laminated to a light polyester outer face for additional abrasion resistance to produce Ultrahigh Dyneema Composite. The result is a composite fabric that is waterproof, super light and relatively strong, with a remarkable structure and dark angular texture that deepens as it ages.

It is important to note that while Dyneema may be the world's strongest fiber, this process is NOT about making the world's strongest fabric. Instead it is about making a lighter and more dimensionally stable fabric to create bags that are easier to carry. While the bags will hold up to wear and are more durable than most other bags in their weight class, they are not particularly more durable than your average heavy nylon bag.
