The silicone sheet can be easily unfolded and fills with water. Through the cap, there is no leaking water even if sometimes the bottle is transported lying in the car or backpack. You can use the silicone sheet on the way as a feeding bowl when the dog is on the go hungry.
The ingenious design of the screw cap makes it possible to screw these on conventional PET bottles, suitable for 38 mm and 30 mm PET bottles. The bottle comes in four great colors and the wrist strap has a reflective material.
