Rating: 4 / 5
I'm on my second pad. My first one suffered from a mysterious leak. The first night I took it out I had to inflate it once during the night. On the second night I used it I had to inflate it 6-7 times during the night. When I got home I carefully inspected it underwater with no obvious signs of leaks. I subsequently tested it with no external pressure and it went flaccid, almost flat, within a half hour four times within a half hour - I returned it to Big Agnes and they promptly replaced it, with what appears to be an upgraded model. It is this new model that I’ve assigned my rating to.
What's new: The fabric is new, it is less slippery, and has a more vinyl feel to it. The new material is more tactile, which was a big plus, as I did not slip off during the night versus the previous version. When packed the pad rolls much tighter and it thus more compact. The width, when inflated is about 21.5 inches, noticeably wider than the previous model. The stuff sack is smaller and has a more compact repair kit. Perhaps the biggest improvement is to the valve - Rather than plastic it is now constructed of what appears to be plastic covered brass.
In order to allow for a more compact model it is possible that the insulation was cut back. My perceptions is that it is a tad colder than my previous one - I don't know this to be a fact however. In just above freezing temperatures, 33-34 oF, I definitely felt cold spots as I shifted around on the pad during the night. However to be fair, I was poorly dressed and had a ultra lightweight bag. With a better bag and more clothing I sure the cold spots will not be a problem.
When fully inflated the pad is wonderfully comfortable - Even sleeping on top of thumb thick twigs, small rocks, and pine cones I didn't feel a thing. It does take some effort to inflate 18- 22 strong puffs, but deflates, and rolls up easily.
Although now happy with my pad, I can't give it more than a four rating - My hope is that its performance does not deteriorate over time.
