ASTM F3340-18 R-values
An R-value (Resistance-value) is a metric used to rate how effectively your sleeping mat resists heat loss. It’s the only way to know how well your mat will prevent your body heat being leeched away by ground temperatures (which can be a lot colder than air temperatures).
This value can be tested in-house but at Sea to Summit our mats are independently tested at a laboratory to precisely controlled standards.
The new industry standard ASTM F3340-18 testing has now been introduced and all Sea to Summit mats released from 2020 onwards are tested to this standard.
