• Three-layer Composite Material: Our water bag is made of a three-layer composite material with a thickness of 0.7mm, Crafted with E-PVC on upper/lower layers and a fiber explosion-proof middle layer. These tubes are very sturdy and maintain a much more defined shape which helps seal the edges of the cover than thinner 0.4mm 1-layer PVC tubes.
• High-frequency welding: Utilizing high-frequency welding with wide seams, our water bags ensure exceptional airtightness and resist high pressure. Withstanding temperatures as low as -10°F (-25°C), fill them 2/3 full to prevent breakage from freezing expansion. Experience durability for over 2 years in low temperatures.
• Screw Tops: A great feature is the screw on filler cap. Most water bags have snap-on style water filling caps, which are difficult to close while keeping all the water inside the bag. The screw caps are much more user friendly and convenient to use. They have a rubber seal on the inside to keep the water from leaking out of the bags.
