Turn your tent into a four star resort.

The down lofting within the mattress keeps you warm and yet compresses well when the mat is rolled up. 

The best of both worlds, airbeds are very comfortable but the cold from the ground will chill yer bones. By adding down, one of the best type of insulation around, an Exped Down Mat can be used on the coldest of ground. 

I love my 9LW, no cold comes from below me, my sleeping bag works to its optimum.

Light foam barriers within the mattress prevent the down from escaping out the valves or migrating between the baffled chambers, eliminating cold spots. These baffles are welded between the down filled chambers, and unlike traditional airmats, eliminate cold spots and create a comfortably supportive and stable air cushion.
