T&C Surf Hawaii Hydro Flask 32oz (946ml) Wide Mouth Stainless Steel Bottle - White, Hawaii Exclusive This water bottle was purchased in Hawaii in October 2025. It can keep drinks cold and hot. It keeps cold for about 6 hours and hot for about 12 hours, making it a reliable bottle. The design of this water bottle, bought in Hawaii, is wonderful and unique to Hawaii. I think you won't see this design often elsewhere. The opening is large, so ice cubes can be put in smoothly. Also, it's very easy to wash because of the large opening. There is only one available. Capacity: 500-999ml
