The NEMO Astro Sleeping Pad is a lightweight pad for getting a good night's sleep while backpacking. The pad features 3" of thickness, horizontal baffles for support and stability, and a soft recycled fabric for quiet comfort. The included Vortex pumpsack is like a dream come true after a long hike. Just snap the pumpsack to the valve, fill the pad with 3-4 bags worth, and you're all set up without huffing and puffing.
