Despite its generous 12-litre storage volume, the pack remains impressively lightweight at just 380g, offering a barely-there feel while providing everything you need for long hours on the trail.

At the heart of the EKLIPSE 12L is its intelligent, segmented storage system. A standout feature is the 360° water-resistant back compartment, complete with a wide-angled access door and five mesh organisers. Frontal hydration and fuel pockets are strategically placed for instant access, with dedicated holders for 650ml flasks and extra-large feed storage areas. Additional zipped shoulder and smartphone pockets, hidden compartments, and versatile pole attachment points make this pack a true all-in-one for serious trail runners.

The custom fit system includes two adjustable chest straps with 20 cm sliders and Instinct’s signature elastic side lacing for fine-tuning on the move. The lightweight, ventilated 3D honeycomb mesh helps wick away sweat and maintain airflow, while the high-sitting profile ensures freedom of movement and unrestricted breathing, even when fully loaded. Built from ultra-tough 30D Nylon 6.6 Cordura® with a silicone liner, the EKLIPSE is engineered to handle harsh weather, rugged terrain, and continuous use.

Whether you're racing through mountain ranges or navigating technical trails over multiple days, the EKLIPSE 12L supports your mission with unrelenting functionality. Its versatility extends beyond racing too, making it a capable companion for fastpacking, weekend treks, and adventure racing where every gram and every second counts.

The EKLIPSE 12L functions as a modular, weatherproof system tailored to endurance demands. Its segmented layout separates essentials by use and urgency, allowing intuitive access even when moving fast. The central 360° water-resistant shell shields your gear from the elements, while the combination of elastic pockets, zip compartments, and compression cords ensures everything stays secure and organised. High-sitting hydration pockets mean you can refuel or rehydrate without breaking stride.

The pack’s fit system is designed for dynamic movement. Dual sternum straps slide to match your chest height, and the double “S” side lacing wraps around your torso for a breathable, stabilised fit that adapts on the fly. Paired with breathable mesh and versatile attachment points, it becomes a customisable shell that moves with you, not against you.
