I have a Barefoot Willie on my bike - cheap - easy to mount in different locations, doesn't swing around, and is easy to put on/take off depending on the length of the ride I am doing. I know it's not sexy, but it is very practical in the hot TX summers. It also allows you to have a coozy in the holder, helps keep the liquids a bit cooler over time. I usually freeze water bottles, keep them in my saddlebag cooler, and drop one in on a stop. Water stay's cold as it thaws. It's easy to grab when the cruise control is running, or your not in the twisties. It does condense, sweat, and drop water droplets as it's warming up, but I don't care about that when it's 100+ outside. Hydration is my number one concern when it's hot. I also don't like donating $1.50 for water at a gas stop.
