I am an EXPED user for life! you just can't beat this pad for packed size, weight, comfort and R value combined. I have this one and the down7 pad love it also, but just to heavy for most backpacking trips where you don't absolutely need the higher R value that's why I bought this one. Anyhow love it and would highly recommend this pad to anyone.
