DromLite Bags provide a large water storage capacity while also being collapsible to a size that matches their cap, making them incredibly easy to carry. This exceptional packability is complemented by their lightweight design, enabling you to move quickly on the trail. Constructed with sturdy film material and RF-welded seams, these bags offer dependable durability. Inside, the enhanced BPA-free food-grade lining ensures superior water taste and can withstand freezing temperatures. In addition, our Hydration Kit accessory adds versatility to the bags, and the new sleek 3-in-1 cap design allows for effortless filling, drinking, and pouring.
