Pacific Outdoors InsulMat SuperLite Mountain Sleeping Pad

What is this? I saw this on the web the other day, and then saw a couple others similar to it at REI.com (online only). Supposedly a 4 season pad with both closed cell foam and an inflatable part of the top that weighs about 12 oz? Yet for REI's similar pads, the weight increases to 23 oz?
I'm just wondering if anyone here has had any experience with these?
EDIT:
Here is a link to the REI website with a similar version of this pad:

And here is the link to the actual one, which seems to be way cheaper than REI's and weigh only 12 oz?? I'm just gonna assume that the description must be wrong.
