I went with Big Agnes on the recommendation of Big Dog, an experienced motorcycle adventurer. I need to pack smaller for my back-country motorcycle campouts. My polyfil mummy bag is warm but bulky. My Theromrest pad is reasonably comfortable but bulky.
The Big Agnes Lost Ranger + Q-Core inflatable pad combined is smaller than either that pad or bag. The Q-Core pad is a blessing - very comfortable
