The zip mouth means you don't have to take the reservoir out all the time to refill or to dry it. As to the tendency of the mouth piece to leak, it has an off position. But I find the simplist solution is simply to blow some air back into the tube after you've finished drinking. Solves the "warm" first gulp as well.

Last summer, I took a long trek in France in some very rugged terrain on the Chemin de St. Jacques. I was well equipped - except for my socks. The result was the loss of three toe nails and a good bit of discomfort on what should have been a lark. Since returning, I have been experimenting with socks - all types. I hesitated at the price of these, but remembering my experience, I gritted my teeth and took the plunge. Glad I did. These socks are all they are advertised to be. They manage to give superior support and padding without excess bulk. You don't feel like the Michelin Man walking around in them. I intend to buy several more pairs. Now all I have to do is take on a part-time job to pay for them!
