Unlike sleeping bags, sleeping mats don’t have fixed temperature ratings. Instead, they’re tested for R-value, which measures how well a mat insulates you from cold ground surfaces.
All Sea to Summit sleeping mats are independently tested to the ASTM F3340-18 standard. This ensures accurate and consistent R-values across brands, making it easier for you to compare mats and choose the right one for your conditions.
To better understand how R-values relate to real-world use, check out our blog post:
