There are fold-up bottles and then there is Bübi Bottle! This is the ultimate multi-use scrunchable bottle. Made out of silicone, it holds its shape but can also be rolled up to take only a small amount of precious space in your backpack or purse. Because it can hold its shape, it’s a convenient waterproof storage place for medicines, snacks, small electronics, matches, or anything small that you need to keep handy and dry. Of course, you can use it like a regular water bottle too – cold or hot – because it’s microwave safe (after removing the cap and carabiner). Add the sports cap, and you have an easy drinking top for on-the-go activities. Definitely a multi-use bottle!
