SAFE TO USE – This is Medical Grade, 26oz Silicone Water Bottle, BPA Free, FDA (USA) and LFGB (Germany) approved. Can be used with one hand, where you squeeze it to drink (you can remove the valve, to drink normally if you want). The cap is also BPA Free, PP Plastic.
SPACE-EFFICIENT – Foldable (by rolling it up) and using the included band to keep it folded.
LARGE OPENING – The bottle has a large hole, so it shouldn’t be a problem to put ice cubes in it (1.8in/4.5cm (insert says 1.9in/5cm which is the outer, hole itself is about 1.8in/4.5cm)). You can also put the bottle in the freezer, but note that if you drink by squeezing, with frozen water you have to wait a while before you can drink.
