Shop our reusable BPA-free and microbial-free water bottles. They are light, foldable and resistant to heat and cold. They provide multiple uses for camping, outdoors, traveling, gym and sports. These unique bottles not only hold water but also are microwave, oven and freezer safe. They are also great for storing and warming up liquid meals. Even good for feeding babies! The bübi bottle is the only bottle that can be used as a medical aide (hot or cold compress). It stores bandages to stay dry and can be used as a pillow when traveling or sleeping on the ground. Place it over a fire (yes, fire!), heat up some water and place it in your sleeping bag to stay warm. The bübi bottle also works great during cold winters. Just place it under your coat and stay warm for the day!
