Just got back from a 3-day trip in the Smokies and this AKSOUL pad held up great. I was worried it might be too narrow, but I didn't slide off once. The integrated pillow is a nice touch, though it’s a bit firm for my liking—I ended up letting a little air out and it was perfect. For the price, you really can't beat the weight. It's light enough for backpacking but comfortable enough for car camping too.
