Thermarest's ultralight three-season camping mattress is perfect for those go-anywhere, sleep-on-anything treks and bivies where every ounce counts. All-new proprietary foams are softer on top for extra comfort and denser on the bottom for extra durability, and the accordion shape packs more comfort into a smaller space than any other closed-cell foam mattress out there.

• Travel Ultralight: Weighing less than a pound, this mattress goes anywhere easily.
• Packs Small: Accordion-style design packs lots of comfort into as small a space as possible.
• Exceptional Durability: Closed-cell foam is incredibly durable, providing an exceptional value and many years of worry-free performance.
