Rab's Ignition 3 Sleeping Bag is comfy for camping and lightweight and packable for backpacking. Its Pyrotec synthetic insulation provides a surprising amount of breathability for maintaining warmth in winter deserts and summer alpine conditions. Because its so breathable, Pyrotec makes the Ignition very packable for compact storage in your backpack. Rab designed the Ignition with a tapered mummy shape that gives more room up top compared to most mummies, and the angled footbox stays snug yet still allows for some movement. The ripstop shell has a high strength to weight ratio, and the polyester lining is soft to the touch. This bag also features an internal draft collar and a drawcord at the hood for secure coverage.
