Why Dyneema®?

We build our Racelite bags with 2.92 oz Dyneema® Composite Fabric because nothing else even comes close. At just 99 gsm, it’s lighter than almost anything you’ll find—and still 15× stronger than steel by weight. Every gram is working overtime: 245 lbs of pull strength per inch, 42 lbs of tear resistance, full waterproof protection, and zero stretch or sag no matter how hard you ride.

While other fabrics add bulk and break down, Dyneema® keeps things light, fast, and built to last. No soaked-through fabric. No heavy, overbuilt designs. No slowing down. Just featherlight performance you can trust for years to come.

If you're serious about quality, performance, and speed, there’s no other choice. This is the world’s strongest, lightest fabric—and we wouldn't settle for anything less.
