I've got two sleeping pads for sale, both used and in great shape. See pics for specs, markings, etc. Both blow up for pics and hold air all night, I just used the Q-Core for a couple night camping and it's great. The Prolite works great too and has a good R-Value and is super compact.

Insulated Q-Core sleeping pads are the ultimate answer to age old quandary of how to pack comfort into the backcountry. Utilizing Alternating I-beam Construction, the Q-Core’s quilted look evenly distributes your weight while the larger outer chambers keep you cradled in the center of the pad. X-Static synthetic insulation keeps you warm and its packability allows you to take it with you anywhere.
