In this cold weather, my husband likes to take a big cup of coffee to work with him to sip on in the shop. One of his common complaints is that his current bottle is too small and he has to drink coffee out of a straw unless he takes the lid off. He works with granite, and there's a lot of rock dust floating around so he prefers to keep the lid on.
The lid is vacuum sealed and has a handy sipping spout, so no more drinking coffee out of a straw for my husband! He can definitely feel a little manlier drinking out of this one! The lid is also dishwasher safe, but not too sure if the tumbler itself is. It's so easy to clean that it really doesn't matter to me though. My husband absolutely LOVES this tumbler and it's the only one he'll take to work now!
If you'd like a king-sized tumbler too, you can get one here:
