Rider Refreshments

What do you guys use for water during longer endurance stints?

I've been doing the camel back thing, but it honestly kind of sucks. If you don't hold the mouthpiece in your mouth the whole stint, it's dang near impossible to find it and get is re-threaded into your helmet while riding. And, having it in your mouth the whole time isn't that great.

Looking at some of the pictures of the professional races, it appears they have a system integrated into their leathers/helmet with just a tube. Thoughts on this?

cant remember where ive seen it , but it looks like they use the typicla camel back mouth piece but attach it to helmet ,then add a quick connect for when they take the helmet off.
think it was one of the old motogp preseason vids....

Mount one of those gerbal water things inside your helmet.... Little redneck engineering.
