Fifteen times stronger than steel. The extraordinary specs of Ultra400X.
Constructed with Ultra400X from Challenge Sailcloth, this advanced material offers abrasion resistance that surpasses conventional nylon while being approximately 20% lighter.

A high-tech fabric made with UHMWPE (ultra-high-molecular-weight polyethylene), it delivers 15 times the strength of steel while offering excellent water resistance. It helps protect contents from light rain, making it ideal for everyday use.

Note: The surface of the fabric may show marks resembling wrinkles or creases. This is a natural characteristic of Ultra400X and does not indicate a defect. Thank you for your understanding.



The interior features a lightweight nylon ripstop liner. Built for durability inside and out, it is made to last.

Smart support for long journeys with reduced burden
The ergonomic harness system, well-cushioned shoulder straps, and back paneling distribute weight evenly, creating a light, comfortable carrying feel even when fully loaded at 20L.
