I bought this insulated bottle for my Son In law for Christmas and he has had it for a year and half now. He works in an outdoor environment all day long in Southern Texas, where it is hot and humid. He fills it up with ice and water and it keeps the water cold all day. It has a handle with convenient hooks on it. He uses the hooks on it to hang it on the Fork Lift, that he runs the biggest part of his day. It has a hygienic cover that has a locking ring, that has stops on it to prevent you from over tightening the lid. The top is equipped with a button on it that can be operated with one hand. My Son In Law says he doesn't even have to stop his Fork Lift, all he has to do is grab his bottle, tip it up, push the button and get a drink. He says it is so easy to operate and that makes it so convenient to have. The Under Armour Hydration Bottle holds 64 ounces of any kind of beverage. It keeps the beverage cold for 8 to 12 hours of use and usually still has a small amount of ice left in it. It is made of hard molded plastic that has the BPA free Double Wall Insulation. My Son In Law says this is one of the best Insulated Bottles he has ever owned and that all the guys that he works with is jealous. The Under Armour Hydration Bottle is not only used for work purposes, it can be used for any outdoor activity. I received this product for full price and this is my honest and unbiased opinion.
