I have the non-insulated version, and its definitely the most comfortable backpacking pad I've slept on in 30+ years. I'm a side-sleeper that thrashes around a lot at night and I tend to stay put and sleep much better on this pad. One note regarding insulation - the deep channels in these bags tend to allow bags to "loft down" below you and therefore provide a slight advantage. However, this works against you if you're using a quilt or ultralight "bottomless" sleeping bag - the deep channels create air gaps that allow cold air to circulate. Therefore I don't recommend it for a quilt or bottomless sleeping bag user. One last thing I'll add - I recently slept in 30º - 45º weather in the back of my F-150 (aluminum bed) on my uninsulated Static V and a 20º bag and felt the cold being sucked out from below me while trying to sleep. The aluminum bed acts as a heat sink and without any insulation, the Static V just wasn't warm enough. I threw a big piece of thick cardboard under me in the middle of the night and was fine after that. I'm now buying the insulated version. The prices fluctuate wildly on Amazon (the insulated Static V in RealTree camo goes from $52 to $90 day-to-day sometimes.
