Montbell has developed a super strong and durable material, orienting the polymer’s molecules of 66 nylon in the same direction. We’ve also blended in hollow fibers to reduce weight by 20 percent from the fiber of same thickness without compromising strength and durability. Weaving densely to make the final material even stronger, yet so smooth applying special processing. The tear strength is 3.6 times stronger than standard nylon. The abrasion resistance has become five times stronger than the nylon fabric with the same denier.
