Water Cube 15 L collapsible water container by GSI Outdoors — 15,000 ml, polyethylene/PP/silicone, 228×228 mm

The GSI Outdoors Water Cube is a collapsible 15 L (15,000 ml) water container designed for carrying, storing and dispensing drinking or utility water during camping, hiking, RV trips and emergency situations. Constructed from food-grade polyethylene with polypropylene and silicone components, the Water Cube folds flat for compact transport and deploys to a stable cubic shape with a 228 × 228 mm base. Its integrated handle and ergonomic tap handle support easy lifting and high-flow pouring while the blow-molded construction increases burst strength and durability.

Advantages

The lightweight, foldable design saves space in packs, vehicles or storage while providing a reliable water supply when access to fresh water is limited. The food-grade materials and silicone seals help maintain water quality for drinking use. The integrated handle and ergonomic tap deliver controlled, high-flow dispensing that reduces spills and makes pouring into pots, bottles or sinks straightforward. Blow molding adds structural strength to resist punctures and deformation under load.

Suitable for

• Backpacking and car camping where compact water storage is needed
• RV and motorhome trips for on-board water supply
• Emergency preparedness and home backup water storage
• Outdoor cooking and washing at campsites

How to use

Unfold the Water Cube and place it on a flat, stable surface. Open the top fill cap and pour water in without overfilling, leaving space for expansion. Close the cap securely and check silicone seals for a tight fit. To dispense, position the container so the tap is over the receiving vessel, then operate the ergonomic tap handle to control flow. After use, drain remaining water, allow the interior to dry if possible, then collapse and fold the container flat for storage. Rinse with clean water when switching between potable and non-potable uses.

Usage recommendations

For drinking water storage, only use clean, potable water and rinse the container periodically. Avoid exposing the container to direct prolonged sunlight while filled, and do not subject it to sharp objects or excessive heat sources. When transporting in a vehicle, secure the folded or filled container to prevent shifting.
