Endorphin Soft Flask 450ml

Excellent flasks! Enjoyed using the one that came with the belt so much that I bought two more. It doesn't leak at all if locked. It's also easy to hold with your hand because of the grippy material. Getting it into the belt fully filled is a little bit tricky but with practice it's easy to do.

The flask that I received with my belt leaked but after a quick email, they sent a replacement quickly that doesn't leak and works well. My only issue is that the Magna magnesium powder I use, stained the flask yellow.

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.
