You should make a 1/16 in pad in torso length, slightly more narrow than the other pads. I'm talking 40 cm x 70 cm x .16 cm. Based on the available pad's stats, this pad would weigh around 0.55 oz, which would be the coolest thing ever. Gotta have bragging rights for "lightest pad on the market", and knock the socks off of any competition. The r-value probably wouldn't even suck very much, at about .4 or so.
But what I'm really interested in is the winter thickness sleeping pad. I want something to layer under a GG Nightlight which will give me a combined R-value of 5 or better. That would mean an Evarest pad with an R value of 3, or approximately .5 in thick. I would be very much excited to see a thicker pad though, and would probably buy the thickest available.
