Following Exped's suite this mat is on the more complicated side of the fence, however once you overcome the initial hurdle of inflating this mat will definitely help in keeping you warm through the colder months of your adventures, especially coupled with a good quality Sea to Summit winter bag.
There is a saying that one layer of insulation underneath is worth 3 on top, and the Exped Down Mat proves this theory. Developed with the Swiss military in the Swiss Alps, it has some solid evidence to this too!
From my experience, here is a summary of what I think of this mat:
Super warm (not too hot in summer either...)
Packs down pretty well
Slightly heavier mat to add to your already heavy winter pack.
Hand pump system takes a long time (but at least you get to practice your CPR) - invest in an Exped Pump dry bag, so worth it!
As soon as you get impatient and start using your lungs to inflate the mat it loses warmth efficiency pretty fast as your saliva clumps the down.
