The Bubi Bottle is looking to make a splash in the ever growing water bottle market. This unique bottle is actually a soft shell bottle that can be flattened and rolled up for easy storage. With real estate in your gym bag being so precious this bottle does a good job of getting out of the way. It weighs just 5.5oz and can tolerate hot or cold beverages and can be placed in the microwave. It is BPA free and dishwasher safe, i really like the idea of using it as a hot/cold compress. This is a must have for the active lifestyle person.
