Ugh the "lightweight means thin and easy to break" thing is so real lol. I had a fancy pad get wrecked by a single, pointy little twig in Utah. It sounded like a balloon popping and I was just done. I switched to a Therm-a-Rest Z Lite foam pad. It's bulky but you can literally throw it on sharp rocks and nothing happens. Slept on gravel with it once and was fine.
