I've been using a Thermorest Z Lite SOL for alpine use for a number of years, like a lot of people I guess, because I don't have to worry about a puncture from anything sharp. Problem is I'm sleeping terribly due to the lack of padding. I am very bony! I constanstly need to roll into different positions through the night, which is probably affecting my partners' sleep as well.
I'd say the mat is warm enough with the sleeping bag I use though, and I like that it's not too wide, meaning I keep to my 50% of the floor space when using the BD First Light tent or bivi bag.
Any recommendations for a mat that will offer a bit more comfort? Anybody dared to use inflatable mats in the loose presence of axes/crampons/ice screws with a bit of discipline? What about down mats? I'd ideally want it for everything from winter mountaineering in Norway to use in the greater ranges. The Z Lite SOL has been warm enough though as I say, but I wouldn't want anything with even less insulation (more is always nice of course). I could carry a mat that was a little heavier if it packed down to a smaller volume, and I don't mind splashing out if it's going to do the job.
