    I use this for mtn biking. I put in my back jersey pocket. Much better then the hard bottles.

    Nice soft flask

    Posted by Monica on 3rd Feb 2017

    My running buddy had been wanting to try a soft flask for a while, so I got him this one for Christmas as part of a runner basket full of goodies. I was more than a little jealous when I received the package, so I'll probably be getting one for myself soon. :)
