The Premium Chill bag water hand spike is designed for dispensing water directly from the bag. For example, when camping, at the beach, or wherever you need water. Keep some on hand for an emergency or a disaster. The hand spike punctures the bag and seals the opening around the spike to prevent leaks. The rugged construction makes this a tool portable and reusable. Bag water will last up three years. Store in a cool dry place and out of the sun light. Comes in three gallon bags or two five liters bag inside one outer storage bag. The inner and outer bag material is degradable, light weight, and ease to handle.
