UltraWeave Technical Details
What is UltraWeave Fabric?
Ultra 200 is a 200d laminated fabric that weighs the same as 100d fabric, but is vastly more durable (because it’s about 60% UHMWPE), with a virtually impenetrable waterproof rating (because it’s laminated with RUV film).
Ultra 200 is in the weight class of 100d Robic nylon, but has twice the tear strength and twice the abrasion resistance as 500d cordura nylon ( which weighs about 3 times as much ).

*the fabric is waterproof, however the CS40 Ultra Backpack has not been seam sealed & is thus not considered waterproof.
What is UHMWPE?
UHMWPE stands for Ultra High Molecular Weight Polyethylene.
UHMWPE fibers (non-branded Dyneema® or Spectra®) are the lightest and strongest fibers commercially available, with a tensile strength 15x stronger than steel. UHMWPE is created by a gel-spun extrusion process which draws out extremely long chains of polyethylene, aligned along a molecular backbone. This alignment effectively transfers load through the fiber for high modulus and strength.
