Have been using Thermarest pads since the mid 1980's... some have failed. Anything that is blow-up will have issues sooner or later, which is one reason I carry a 1/4" Evazote pad to use on top of any inflatable.
Yeah, I had a closed-cell foam pad that was stashed in the four-wheel-drive at the trailhead and I debated taking that pad as well, but after considering bulk and subsequent noise factor while negotiating dense oak and dense pinon pine and dense mountain mahogany )all combined together) I decided to stay as compact as possible while chasing whitetails in a very remote stretch of mountains along the Arizona/New Mexico border. After my first night afield, though, I was wishing I'd just brought the closed-cell pad and had just left that Thermarest behind.
