The Comfort Deluxe SI Mat from Sea to Summit is an oversized, self-inflating sleeping pad with 4 inches of plush thickness for car camping, outfitted with DeltaCored foam inside a 30-denier top / 75-denier base body.
As of January 1 2020, all sleeping mat manufacturers will test mats for R-Value in independent labs using the ASTM standard F3340-18. Having one test standard provides clarity and transparency to consumers and allows comparisons across brands. Since the standard was published, Sea to Summit has continued to work with other sleeping mat manufacturers and with accredited labs to ensure that the testing is accurate and representative of actual mat performance. The new test protocol will see some changes to previously published R-Values. It’s important to note that where values do change, it doesn’t signify a drop or increase in warmth—it simply means they have been tested using a slightly different scale. The packaging of some mats will still carry the previous R-Value, but the mat itself has not changed.
