A light weight and protective synthetic insulation make the Rab Ignition 3 Sleeping Bag excellent for backpacking from fall to spring. Rab's proprietary Pyrotec insulation resists water, compresses, and is surprisingly lofty, and the ripstop shell offers lightweight durability while the polyester lining feels soft to the touch. The bag's mummy shape tapers down to the legs in order to reduce weight and bulk, and the angled footbox prevents your feet from feeling squished. Rab added an adjustable hood and a draft collar to seal out cold, and there are bags available with the zippered closure on either the left or right side. Rab also included a compression sack for your convenience.
