The Hydration system

One of the many things I want to do is extend my ride distance, and if done I would need a better hydration system. For real long rides I have the CamelBack system, but I hate maintaining it. For moderate rides I find I need two 24 oz water bottles, but if I use the main bottle on the front boom it is a pain to remove the one under the seat. Actually it is easier to remove than to replace, so something had to be done. Then a new product came along called the Smartube system, which consists of different bottle caps to fit everything from a water bottle you buy in the grocery to a bike bottle. This system even has a insulated tube cover available as an option. I tried to purchase one in the USA, but the distributor has not signed a deal with the company. They are easy to obtain in Europe and the UK. Jeff from Rebel-Cycles in Canada is getting some so I guess I will buy mine from him, unless I find it in the USA. What makes this system so unique is the one-way valve in the top that allows air to enter to prevent collapse of the bottle when liquid is removed.
