It’s incredibly lightweight for a 12-liter vest, and once it’s on, it feels like part of my torso. The breathable fabric keeps things cool over long hours, and the expandable zipper is a clutch feature for adjusting storage as I shed layers. The included soft flasks ride secure and accessible, making this vest a true workhorse for distance missions.""We count on the Salomon S/Lab Ultra 12L Set Hydration Vest when our longest days demand unwavering stability, efficient hydration, and lightweight comfort.
