Best ever flask that I've used. The product is highly recommended. No leaks and always comes in a handy. Technical support also very efficient handling returns. Just so amazing.

Great flask… amazing customer service! The first flask I received had a flaw. I notified the team at Endorphin and they sent me a new one immediately.
