A 6-liter collapsible water reservoir with a spigot and a filter-thread outlet.
Shipping: calculated at delivery
The Gravity Water Reservoir is a 6-liter collapsible bladder in BPA-free food-grade TPU. A wide fill opening at the top makes it easy to scoop from a stream or fill from a tap. A push-button spigot near the base dispenses water for cooking and washing without lifting the full bag.
The lower outlet uses a 28 mm standard thread that connects to inline hollow-fiber filters, allowing hands-free gravity filtration when hung from a branch. Empty, the reservoir rolls flat and weighs 180 g. A webbing handle doubles as a hanging loop.

Filters hands-free
Hung it from a tree, threaded my filter onto the outlet, and let gravity do the work while I set up camp. Six liters is enough for two people for an evening. Rolls up to nothing.

Spigot drips slightly
After a couple of trips the spigot weeps a little even when closed. Not enough to matter much but worth a note. The gravity outlet thread fit my filter perfectly.
