How do you like your Exped Downmat? I was thinking of getting one.
I can comment on mine...It is the "real deal" in cold weather or if you have sleep, back, and/or hip related problems. Very warm and comfortable. Provides more than enough loft to help me wake up without issues from bad hips and arthritis in my lower back and hips. In fact besides a hammock it is the second best sleep system I own. I've slept on frozen hard packed ground and even with my arthritis as bad as it is...no problem.
I have last years model and this year's newer model is superior. The only nemesis is the pump system. The newer model is suppose to have fixed that. Also it takes some getting used to the valve (mine leaked on me one night). The valve I later found out was due to operator error and not product defect. However, you've gotta figure it out.
Highly recommended...especially with the newer pump system.
