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.
