New for 2012: Forty years ago, Thermarest patented the first self-inflating mattress and introduced the world to a new level of backcountry comfort. They are celebrating their anniversary with a limited edition mattress featuring the original logo and colors. The 40th Anniversary Edition mattress may look like a throwback to the first Therm-a-Rest® mattress, but it features cutting-edge technology that offers excellent comfort, packability and 4-season warmth. The foam in this mattress is the lightest, most compressible foam Thermarest have ever used, allowing greater comfort without additional weight or bulk. Stuff sack and repair kit included.

• Limited Edition: 1972 logo and color, with individual serial number, available for a limited time.
• Comfortable: Two-inch thickness provides a high degree of comfort and support.
• Efficient Warmth: The 40th Anniversary Edition features the lightest, most compressible foam used in any of our mattresses, allowing 4-season warmth without extra weight.
• Visible: A glow-in-the-dark valve makes it easy to find at night.
