2.8L All Terrain Vest

**This is a preorder. Orders will ship in September 2026**

The RSVR All-Terrain 2.8L Endurance Vest is built for extended days and high-output missions where water capacity, stability, and efficiency are non-negotiable. Pairing a front-mounted nutritional vest for immediate access to fuel and essentials with a patented aerodynamic 2.8L bladder that conforms closely to the user’s back, the system distributes weight evenly while maintaining a slim, low-bounce profile during continuous movement. Engineered from the body outward, the shaped rear bladder reduces standoff and drag while storing more fluid in less space than traditional designs, allowing athletes to carry increased hydration without added bulk or compromised mobility. Designed to scale with distance and conditions, the vest supports long-duration endurance efforts, variable terrain, and changing environments—delivering a balanced, adaptable hydration platform for athletes who need one system that can handle bigger days in the mountains.
