In reply to buzby:
Another very happy Downmat 7 owner.
The best bit of kit I have bought in a number of years. I do a lot of camping, often where the ground is very bumpy, and those of us with downmats have been the only people getting good nights' sleep.
It is the warmest and most comfy thing I have slept on in a tent.
If I was to buy again, I might go for the Downmat 9 for even more warmth and comfort.
