DromLite Bags

Carrying bulk water in the backcountry usually forces a choice between delicate ultralight bladders and heavy, stiff expedition jugs. MSR built this reservoir to eliminate that compromise, pairing a rugged 200-denier Cordura exterior with a food-grade polyurethane lining. The woven textile shell shrugs off rough granite slabs, pine needles, and overloaded pack interiors that easily puncture conventional transparent film bladders, yet it rolls down tightly to the diameter of its screw cap once emptied at camp.

In the field, versatility centers on the multi-function 3-in-1 cap. It features a wide opening for rapid fills and filter integration, a medium pour spout for filling cook pots, and a small flip-spout for a controlled hand-washing or dish-rinsing trickle. Perimeter webbing loops make it simple to hang from branches or lash onto the outside of a loaded backpack during long dry stretches between desert water sources. Because the material is flexible, balancing the bag while pouring single-handedly requires two hands when full.

Against standard TPU hydration bladders from HydraPak or Platypus, this bag trades total transparency for vastly superior abrasion resistance. It weighs noticeably less than MSR's heavy-duty 1000-denier Dromedary, making it the practical sweet spot for backpackers, packrafters, and alpine climbers who need dependable multi-liter capacity without carrying dead weight.
