Need to pick up a 2nd mattress so I can finally go backpacking / camping with friends.
I already have a Thermarest Trail Lite, which has an R value of 3.4. I find it comfortable, but it's a bit big at about 5L of space used.

I've been looking for a new pad. I seemed to read a lot of good things about the Klymit Static series being a good value. I can pick up the Static V for around $35, or the Static V Insulated for around $50.
The V has an R value of 1.3, the Insulated at 4.4 — difference in volume is about 1L vs 2.5L of space (still half the size of the Trail lite).
The thing is, I'm not really sure if I even need the insulated version.
I generally camp out between April-October and have a 32 degree down bag. I usually tent camp, but if I pick up a cheap fare, I've flown out (like to Salt Lake City) and just brought a hammock.
In reality, with an R value of 1.3, how comfortable would I be with general 3-season camping? Or am I asking for trouble?
