For paddlers and backpackers who prefer to travel light, leaving a dedicated clean reservoir at home can be a meaningful weight and space saving on a longer trip.

The GravityWorks Universal Bottle Adapter connects your GravityWorks filter directly to a wide range of water bottles and hydration reservoirs, letting you filter straight into the vessels you're already carrying. The modular design means you bring only what you need for a given trip rather than hauling the full system every time out.

It's a small accessory that adds real flexibility to an already capable gravity water filter setup, and pairs well with the GravityWorks Push-Pull Cap Adapter if you want to cover even more bottle compatibility. Ultralight and compact, it won't register on your pack scale but you'll notice the clean reservoir you left behind.
