My daughter is a dancer that trains at least 5 days a week, and we were in the market for a new thermos.  The light green color is really soft and pretty, but is unisex enough for anyone to use.  She takes this bottle with her to class and it keeps cold the entire evening.  I’ve also used it during the day for warmer drinks, and it insulates either way.  Easy to clean, makes it even better.  It’s a win for our family.
