Description

Built with breathable honeycomb mesh, the Evolution 7L promotes airflow and helps wick away sweat while remaining durable and secure. Storage is carefully thought out: from dual 650ml hydration pockets and front feed pockets to rear compartments for rain gear and safety essentials. You’ll also find a 100ml shoulder pocket with safety whistle, elastic upper pole storage, and multiple pole carry options to suit your preferred style.

The vest’s standout feature is its fully customisable fit. It uses adjustable chest straps on 20cm sliders and an innovative “S” side lacing system for fine-tuned comfort and stability mid-race. Whether you're carrying a water bladder, bottles, or soft flasks, the Evolution 7L adapts to your fuelling strategy, making it an essential bit of kit for endurance athletes tackling changing conditions and long distances.

From rapid access to hydration and nutrition to unmatched stability on technical trails, the Instinct Evolution 7L helps you run further with freedom, ease, and confidence.

How does it work

The Instinct Evolution 7L is designed to offer freedom of movement, hydration flexibility, and immediate accessibility, even during demanding races. It sits high on your torso, which not only keeps the weight stable but also enables quick access to hydration flasks, nutrition, poles, and gear. The double vertical rear compartments are bladder-compatible and combine with rear pockets for a streamlined setup, whether you prefer bottles, soft flasks, or a hydration reservoir.

The vest’s adjustable fit is driven by front sternum sliders and an “S” lacing system that adapts to your body in motion. Breathable mesh helps prevent overheating, while intelligently placed compression cords secure items in place. Together, these features create a race vest that remains secure and functional across any terrain or distance.
