Lightweight and breathable, this 4L running vest includes dual soft flasks, supports a hydration bladder, and offers secure, bounce-free storage with adjustable fit and multiple pockets.

The Salomon Active Skin 4 Set Unisex Pack with Bottles is a streamlined hydration vest engineered for beginner to intermediate trail runners who prioritise lightweight comfort, intuitive access, and efficient storage. With a close-fitting design, this 4L pack is built for movement, breathability, and bounce-free performance over shorter to mid-distance adventures.

It includes two 500mL soft flasks for on-the-go hydration and is bladder compatible (up to 1.5L, bladder not included), offering versatile hydration options depending on your training needs. The updated SensiFit construction wraps the body like a second skin using soft stretch fabrics, inner mesh, and Quick Link adjustable sternum straps for superior fit and stability. The 3D Comfort back system with 3D Airmesh shoulder straps maximise airflow and ventilation, keeping you cool even during intense efforts. Equipped with multiple secure and stretch pockets - two chest pockets, one back compartment, and one front zipped pocket - the pack provides optimal organisation for essentials, snacks, and gear.

Added features like the bungee elastic cord for jacket storage and compatibility with the Salomon Custom Quiver make this pack a versatile companion for trail running and outdoor pursuits.
