Overview
The GSI Outdoors 20 liter Water Cube is a collapsible base camp water carrier made from blow molded polyethylene and polypropylene, built with an integrated pour tap and carry handle for car camping and group trips.
This is sized and shaped for a campsite table, not a pack, so the 20 liter capacity is a strength for a group and a bulk item for one hiker. The blow molded construction is meant to resist bursting under the weight of a full load, and the whole thing folds flat once empty for the drive home. GSI backs it with a lifetime warranty against material and workmanship defects.
- 20 liter capacity
- Integrated pour tap
- Collapses to 10.5 x 10.5 x 2.5 inches empty
- Lifetime warranty against defects
Who it's for
Fits car campers, group sites and anyone who wants one central, dispensing water source at basecamp. Not suited to solo backpackers who need something to carry on the trail rather than set up at camp.
Pros and cons
- Collapses flat for storage when empty
- Built-in tap allows hands-free pouring
- Backed by a lifetime warranty
- Bulky and heavy once filled with 20 liters
- Not designed for backpacking use
- No filtration, just storage and dispensing
Performance notes
The built-in tap is designed for a high flow rate so filling pots or bottles does not turn into a slow drip, and the carry handle helps with lifting a full, heavy cube. Once emptied, the blow molded body flattens down to a small footprint for the ride home or storage in a garage.
