Commemorate 40 years of backcountry comfort with the Thermarest 40th Anniversary Edition Sleeping Pad for women. Thermarest designed this version with a woman's body in mind, adding insulation in the torso and foot of the mattress to provide extra warmth where women need it most. Setting it apart from their standard issue mattresses, the 40th Anniversary model includes the original Thermarest logo and yellow color of their 1972 self-inflating pad. Don't worry; you get the latest modern innovations and fabrics including a glow-in-the-dark valve and the lightest, most compressible foam that Thermarest has to offer. It's the perfect choice for all-around 4-season camping with the added flair or the retro logo and look.
