■ Ultimate Next-Generation Material: Ultra400X

Overwhelming Strength and Lightness: Made with Challenge Sailcloth's Ultra400X. This fabric, made from UHMWPE (Ultra-high-molecular-weight polyethylene), boasts 15 times the strength of steel per gram and achieves approximately 20% weight reduction compared to conventional nylon etc.

High Level of Water and Abrasion Resistance: It has water resistance to protect your belongings even in harsh environments, and overwhelming abrasion resistance.

※ Due to the nature of the material, wrinkles and crease-like marks may be visible on the surface, but this is a characteristic texture of ULTRA and not a quality issue.

■ Minimal and Meticulous Storage Design

8.3-inch Tablet Compatible: The main compartment is equipped with a padded pocket. Small tablets such as iPad mini can be safely stored.

Security and Convenience: Updated for security with a rear security pocket to protect your passport and wallet, and a hidden pocket for smart trackers (AirTag etc.).
