Rab Mythic -6C / 20F Sleeping Bag No Wasted Grams. No Cold Spots. When a bikepacking route pushes into alpine territory or a summit camp drops below freezing, the bag you're sleeping in matters as much as the kit you rode in. The Mythic -6C / 20F is the answer for riders and alpinists who refuse to carry weight they don't need. The shell is built from Pertex(R) Quantum ripstop to stand up to mountain conditions without adding bulk, and the heat-reflective TILT lining works with the down fill to cut radiant heat loss without adding any meaningful weight. Inside, the L. O. F. T 3D(TM) baffle construction uses helix-shaped baffles to lock down in place and eliminate cold spots, so the warmth you carry in is the warmth you feel. Hand-filled in Derbyshire, UK, this bag has never been compressed before it reaches you - which means the down arrives with full loft intact and ready to perform.
