The Instinct X8 - 18L is purpose-built for serious endurance athletes, fast-packers, and outdoor adventurers seeking a lightweight yet highly functional pack for long distances and varied terrain. With a spacious 18-litre capacity and weighing just 546g, this pack delivers on both carrying capacity and comfort, without compromising performance.
About X8 - 18L
Accessibility is at the heart of the X8’s design. A large rear opening gives you a clear view into the main compartment, letting you grab gear quickly without digging around. The integrated 3D mesh back panel and shoulder straps are cut from a single piece to eliminate pressure points and avoid chafing, even over long distances. Whether you’re navigating steep climbs or crossing exposed ridgelines, this pack stays breathable, stable, and irritation-free.
Frontal storage is another standout feature. The X8 includes space for 2 x 600ml soft flasks (optional), two oversized zipped pockets, two stretch mesh pouches, and two zipped shoulder compartments, allowing you to keep essentials like gels, gloves, or a phone right at your fingertips. On the back, the weather-resistant Cordura® Nylon 6.6 ripstop main compartment holds over 9 litres, with additional top and bottom mesh pockets for rapid organisation. It also includes a dedicated 2.5L bladder sleeve and multiple attachment options for poles, ice tools, and even a tent or sleeping mat.
Whether you're pushing through an ultra-marathon or heading out on a multi-day mission, the X8 - 18L adapts to the demands of your journey. Durable, intelligently designed, and hydration-ready, this pack offers a perfect balance of comfort, function, and weather protection, so you can go further with confidence.
How does it work
The Instinct X8 - 18L combines clever design with premium materials to deliver exceptional performance in all conditions. Its back panel and shoulder straps use a seamless 3D mesh construction to eliminate friction and hot spots, providing all-day comfort. The large rear access panel offers complete visibility into the main compartment, while stretch mesh and zipped pockets on the front and sides keep essentials within reach.
Hydration is a priority: the front holds two 600ml soft flasks for quick access, and a dedicated internal sleeve houses a 2.5L bladder. Weather resistance comes from a tough Cordura® Nylon 6.6 ripstop body, while gear attachment loops let you secure poles, an ice axe, and even a tent, making this pack highly adaptable for different adventures.
