My 3 liter hydration engine came in yesterday. I haven't had a chance to do anything with it as yet, but I'm impressed by the thoughtfulness that went into the design.
One of the aspects that really sold me was the fact that the hoses are of a quick-disconnect design. For those of us who have Rally 2 Pro jackets, that's a major benefit, because tearing open the jacket layers to run the hoses is a real pain. I'll still have to open it up to get to the pocket where the reservoir sits, but it will be much easier to do refills this way.
Why did I drink all of the ingredients for vomit?
