Update from Challenge: After feedback from thousands of packs in the field from many brands, we have decided to improve the bias strength and improve longevity of Ultra by inserting a very thin, black Ultra CrossPly yarn at 45 degrees to the warp. As of now, White, Gravel Gray and Silverado have been transitioned to the "X" variant, but others will be updated as they arrive.

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

If you're interested in a full breakdown of the technical specs on Ultra, check out our fabric data sheet and/or read this article by Pa'lante Packs.

Challenge Ultra 200 is a laminate fabric comprised of the following layers:

- 200D UHMWPE/polyester plain woven face

- Ultra Crossply yarn @ 45 degrees (X variants only)

- 0.5 mil Recycled PET film backing

If your application requires the lightest, strongest, most durable and waterproof fabric that you can possibly buy - this is it.

Sold by the Half Yard. For example, enter a quantity of "4" to receive two linear yards of material, measuring two yards (72") in length by the listed width of the material (check specs tab).
