Completely redesigned from the inside out and R-Value rated by a third party, the Q-Core SLX is lighter, tougher, easier to inflate/deflate, packs smaller and sleeps warmer with PrimaLoft® Silver Insulation. The Q-Core SLX ups the ante on quilted comfort in the backcountry with offset I-Beams that create incredible multi-directional support and stability. When it comes to superlight, three-season comfort, this pad stands alone. Save your breath for the miles ahead, and use the included upcycled pad inflation sack to inflate.

From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.
You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.
In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.
