This fabric has the same construction as the Ultra 200 except with twice the UHMWPE content, making this a great choice for high abrasion usage. We use this on the back panels and bases of our range of Ultra packs.

Owing to the way this fabric is constructed, we tape the seams so Ultra 400 backpacks will be VERY water resistant.
