You'll never look back...
This pad is without question the best backpacking pad I've ever used, and I've used a lot! I've used this pad several times and I'm certainly a believer. My philosophy is that I'll throw a little extra size and weight on my back for a good night sleep in the back country, with this pad that's not necessary. I got the wide- long mostly for extra width and it's neither bulky or overly weighty. I have mine rolled down to about half the size of the stuff sack that comes with it. The sides of this pad are slightly raised to help kind of cup you in which I love, cause I regularly rolled off my old pads at night. Bottom line, I believe this pad is second to none for backpacking comfort. I plan to buy a second one for my wife to use, probably in the SL version to shed a few ounces.
