Lightweight and simple, the Astro™ and Astro™ Lite offer a plush 3.5-inch thickness and lateral baffles. Lateral baffles are more comfortable than vertical baffles, and prevent the sides of the pad from curling around your body. The large Pillow Baffle™ at the head end of the pad ensures that your pillow doesn't slide off in the middle of the night, and gives a couple extra inches of height to bolster your camp pillow. Updated for 2019 with zero-profile, multi-functional, micro-adjustable valves, the Astro™ continues to be the durable, reliable, and value pad for every adventure. Features. New zero-profile, multi-functional, micro-adjustable valve with fast deflation. Astro™ Lite's 20D fabric set shaves weight for ultralight adventures. Pillow Baffle™ keeps your pillow in place and adds loft. Textured polyester surface is softer, quieter, and has less stretch than nylon. Details. Temperature: 35 to 45F / 2 to 7C. Min.
