    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 400 is a laminate fabric comprised of the following layers:

    - 400D UHMWPE/polyester plain woven face

    - 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 qty of "4" to receive 2 linear yards of fabric.

Amazing quality

Amazing quality. Beautiful product.

Thank you for the kind words! We are so happy to hear that you are loving the Challenge ULTRA™ 400!

Challenge 400 - Great fabric but hard to cut

Really nice fabric. Definitely a sturdier feel than the 200. I use it for the bottom of bags. It is almost impossible to cut with a pair of scissors. A razor wheel works better but, still is a workout to cut through it. Sews easily - used a #16 needle and Mara 40 thread.

Thanks for leaving a review, Al! The ULTRA 400 is definitely a beefy fabric and it helps to have a sharp blade but still might take some patience. Enjoy!
