Ultra Fabric

Unless you've been living under a rock, you've probably heard the buzz around Ultra fabrics from   Challenge Sailcloth  - and for good reason.

Ounce for ounce, Ultra fabrics are likely the strongest, most durable materials you can buy on the market today.

If that wasn't enough, they're also insanely waterproof and seam tapeable. 

Said another way, a project or product using Ultra can handle more abuse and ultimately last longer compared to using similar weight - or even significantly heavier - standard nylon and polyester. 

Speaking of products, Ultra fabrics are already being used by some of the leading backpack and bag companies in the world such as   Pa'lante Packs,   LiteAF, and many more. 

The performance of Ultra starts with the yarn that's used to weave it - UHMWPE. 

Unlike all other generally available material options to date, Ultra combines a UHMWPE woven face with a laminated film backing to produce a fabric that has:

  • Extremely high tear and tensile strength
  • Maximal cut, abrasion, and wear resistance
  • Super high and long term waterproofing
