Looks like a great product, especially when looking at the weight to r-value, thats a big insulator. I used to use an Exped downmat and it was rubbish. Holding the thing up to the sunlight reveals the down didn't spread evenly but left uninsulated areas where the down had slid into clumps. The info claims to have fixed this problem somehow so it could be a great product.
Is there a reason this mat is square rather than mummy shaped?
