I led trips in Northern Maine for the past 10 years and was constantly searching for a sleeping pad that could handle the extreme cold, -30F, that we suffered through up there. Before this pad I had to carry a thermarest and a ridgerest- otherwise you could feel the cold seep through. With this pad, I have never felt the cold. It literally adds a few degrees to your bags comfort rating. I don't roll around much, so I can't really comment on how easy it is to stay on... you're pretty high up with the pad fully inflated. Using the pad with a regular sleeping bag worked great- using it with a Big Agnes bag I found the pad so big that there was hardly room left for me... and I'm only 5'8" 160lbs... a friend borrowed my gear and literally couldn't zip the bag shut. If your a small individual, Big Agnes also stands for BA gear... it performs well and is super durable. Considering that I could only carry one pad, this system saved weight. For summer or fall travel, it's overkill and heavy.

I bought the Big Agnes Dual Core, after I spent a very cold night in a snow cave while sleeping on a Thermarest. I needed something that was light yet comfortable and could insulate. The second trip out I had the Dual Core, there was no comparison. I woke up warm and felt well rested. The difference was amazing. I'm 6'3" so it was a little short and narrow but at my size you have to sometimes make do. Overall I would recommend this pad to anyone who is winter camping.

It keeps you warm, is light weight, and fits perfectly into the sleeve of many Big Agnes bags. Packs small.

So so comfortable. Now I now that is not a full sentence, but that is what I sound like when I am lying on this pad, incoherent! I got this for Christmas and can't wait to try it out in the real world. I was a bit worried about rolling off the mat, but was able to fix the problem by letting out a bit of the air. If you are sick of waking up with sore hips when you are camping (especially the gals out there), get this pad!!
