Completely redesigned from the inside out and R-Value rated by a third party, our three-season Insulated Q-Core Deluxe provides the ultimate sleep experience when comfort and performance is the priority. I-Beam construction reduces pack weight and provides consistent stability with an ultra-comfortable, super-quiet quilted two-way stretch top for a cushioned pillow-soft sleeping surface. Larger outer chambers keep you comfortably cradled in the middle of the pad and built-in advanced heat-reflective technology using PrimaLoft® Silver Insulation will keep you warm throughout the night. Save your breath for bagging 14ers, and use the included upcycled pad inflation sack to inflate.
Materials & Construction
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.
