Weighing just 12.5 ounces with the bladder included, it sits close to the body with a second-skin fit that minimizes movement during faster efforts. The 12L storage capacity gives you enough room to carry essentials without the vest feeling bulky or restrictive.A low-profile 1.6L insulated bladder reduces sloshing and keeps water cooler longer, so hydration stays accessible and refreshing across extended efforts. Thirteen exterior pockets distribute gear across the vest, giving you dedicated spots for nutrition, a phone, or small accessories without breaking stride.
