Takeya Thermo Flask

Takeya Thermo Flask is one of the more durable water bottles I've used. They suffer the dishwasher poorly but the damage has been whole cosmetic. They keep cold beverages cold for very long periods of time and have a large enough opening to fit a good sized bottle brush.

I like these so much that I now have four of them three or witch you can see here. The black one on the bottom I painted green to keep folks from swiping it at the gym.
