This is the first year I will be winter camping in the mountains (most of my winter camping in the past has been in milder conditions) and was wondering about the 1/8 inch verses the 3/16 inch Gossamer Thinlight pad and which I should be considering for an additional sleeping pad.
My gear at this time will be a full length Neoair a Western Mountaineering Versalite 10 degree bag, normal base layers and down sweater. I sleep a bit warm but realize I should probably add an additional pad for the neoair to add a bit of warmth. Am I going to see a huge amount of difference in warmth between the 2 sizes while carrying double the weight, or will the 1/8 inch pad be enough between the ground and my Neoair for warmth for these temperatures?
Thanks,
