I use this bottle in my travels, so it fits perfectly in the side mesh pockets provided for this purpose on my backpack and did not feel at all. It is designed to be manipulated with one hand, very practical bike for example. The closure is secured by a powerful hook, you can not end up with the open bottle by accident. Guaranteed BPA-free plastic is dense, does not bend at all and does not break when unexpected fall The unit is scheduled to go in the dishwasher. The design is very nice with a nice ergonomics and a wide range of colors.
