It’s so simple and inexpensive, plus it makes cooking and cleaning at a campsite so much easier with instant water at the twist of the tap handle. The Folding Water Cube comes in three sizes, and it features an ergonomic handle and a simple tap. GSI Outdoors reports they’re made with a proprietary blow-molding method for superior burst strength and added durability. The food-grade polyethylene material is pliable and easy to fold. There are other containers on the market, but few of them stand up alone, are easy to open and close with one hand, or pack down quite as compact as the Folding Water Cube. MSRP: $7.50 – $10. //
