LIMITED EDITION X-PAC CORE BACKPACK Technical. Durable. Weather resistant. Same CORE Backpack functionality. A completely different material. Built with X-PAC® X42 — a high-performance laminate developed from advanced sailcloth technology. Born from materials engineered to perform in demanding marine environments, X-PAC applies the same principles of strength, low weight, stability and protection from the elements to everyday carry. X42 is built around a tough 420-denier nylon face, reinforced with X-PAC’s distinctive X-PLY® fibre grid and bonded to a waterproof film backing. The result is a material that is highly durable, abrasion resistant, lightweight for its strength and built to handle wet conditions. That visible X-pattern isn’t just for looks. The X-PLY® reinforcement helps add structure, control stretch and reinforce the fabric under load. FEATURING: 420D nylon face fabric Reinforced X-PLY® construction Waterproof film backing High abrasion and tear resistance Excellent strength-to-weight ratio Distinctive technical X-PAC finish Dual bottle pockets 16” Internal laptop sleeve Sealed shoe compartment External lifting belt attachment
