This is the Steady Dog Stainless steel 20 oz vacuum sealed water bottle. It is a wonderful water bottle . I have had ice stay cold for longer than 12 hours. It is a great bottle to drink out of. It has a wide mouth and it also has a extra lid. It is very easy to pack . It has a ring that I can pack on my finger . It is very light to pack . Even though it is so cold it is not cold to the touch that it freezes my hands . It is a wonderful water bottle. http://www.amazon.com/Stainless-Insulated-Interchangeable-Sports-Compatible/dp/B018DSSR46/ref=sr_1_80?ie=UTF8&qid=1457825392&sr=8-80&keywords=insulated+water+bottle
