MSR DromLite 6L Water Reservoir – Collapsible, BPA-Free, Grey, USA-Made

Meet the MSR DromLite 6L Water Reservoir, a high-capacity hydration bag that folds to the size of its cap. This clever design pairs rugged durability with trail-ready packability, letting you carry ample water without unnecessary bulk. The exterior uses a tough 1,000‑denier fabric, while RF-welded seams keep the vessel secure and leak‑resistant. Inside, a BPA‑free lining helps keep water tasting fresher across a range of temperatures, and the material is built to handle freezing conditions. Accessories like the Shower or Hydration Kits expand its versatility, making the DromLite a flexible choice for a variety of adventures.

Designed for real-world use on the move

On the trail, every ounce counts. The DromLite’s capacity scales with your trip, yet it collapses down to the size of its cap when empty, freeing valuable pack space for other essentials. The included MSR 3‑in‑1 cap makes filling, drinking, and pouring straightforward, reducing stops and awkward maneuvers at sources or at camp. The 6L version measures 11.3 x 20.6 inches when full and weighs a lean 5.7 ounces, delivering a practical balance of water capacity and lightweight design.
