Take your hydration on the go with the SkyyHi Collapsible water bottle. Through the use of highly durable material, this bottle can go from 9 inches to just 5.75 inches in seconds. This incredibly portable bottle has unique design that allows the edges of the bottle to fold. The SkyyHi water bottle uses hard-wearing silicone to expand and collapse as often as you need. In addition, the SkyyHi water bottle is complete with an opening large enough to fit ice cubes. Finally, the lid gives an air-tight seal so the bottle is totally leak-proof. The SkyyHi water bottle can hold 9 ounces of liquid when collapsed and 18 ounces when expanded. It’s the perfect solution for the gym, you commute and everywhere in between.
