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 teep you warm throughout the night. Save your breath for bagging 14ers, and use the included upcycled pad inflation sack to inflate.
