Rated 4 out of 5 by Bigtooth A Good Supply of COLD Water for Summer Hiking
Once you get over the large size you will enjoy the 64 oz of cold water or hot beverage. The cap could be less flexible as it is easy to cross thread unless you are careful.

Good size of a 64 oz. Keep water hot and cold in 6 hours. When you need a 64 oz water bottle. This is a good choice.

Rated 5 out of 5 by Chippersen12 Hydroflask
We purchased this for a friend and used it right away. While vacationing for a few days in the Berkshires we found a solar brewery. This baby proved excellent in keeping the "brew" cold for us to enjoy. We liked the hydroflask so much that we purchased another one for ourselves! Great product.

Rated 5 out of 5 by canarymary the best for cold liquids
I have the hydroflask in the 40 oz and the 64 oz. It keeps cold liquids COLD for 24 hours. There is still ice present after 24 hours. It does not impart any flavor to the beverage. A first rate product.
