    Good soft flask

    Posted by Unknown on 15th May 2019

    I have bought two of these recently. One developed a pinhole leak almost immediately. I don't know if it was faulty or something happened but it is disappointing. The other one is great and served me well during my last ultra.

    Nice bottle

    I went on a run and it took a little big to get use to the feel. I could put it in a pocket or hold it. I was nice towards the end to be able to put it away and not have to hold an empty bottle!
