Love this for the gym. I put ice cubes in along with the water and after my 2 hour workout they were still ice cubes and had not melted all the way into the water. The water stayed icy cold. I hate drinking warm water during my workouts so this is amazing. The bottle construction is solid. It is almost like a soup thermos in construction just not as heavy. It is lightly weight so easy to carry around the gym.
