What Our Gearhead(R) Experts Are Saying: "This vest is perfect for long trail runs or even light hikes. The fit feels secure without bouncing, and the mesh harness is super breathable. I like that it comes with soft flasks up front, but it also has room for a bladder if I need more water. Plenty of pockets for gels, a jacket, or even poles."We bring along the Salomon Active Skin 8L Hydration Vest when we need hydration and gear storage without the bulk of a pack. The lightweight nylon body paired with a 3D mesh harness delivers a breathable, chafe-free fit that moves with us mile after mile. Dual chest pockets carry the included 500ml soft flasks for easy sipping on the go, while a reservoir sleeve in back is ready for longer hauls. With 8 liters of storage, this vest has space for snacks, layers, and essentials, while cinch straps stabilize lighter loads so nothing shifts on fast-paced descents. Thoughtful details like stretchy mesh pockets, a low-profile fit, and reliable durability make the Active Skin a training-day staple and an ultra-distance must-have.
