The Robens Spire III -9°C Sleeping Bag is the warmest bag in the Spire range: a synthetic mummy bag with OneThermo® insulation, a -3°C comfort rating and a -9°C limit, for winter camping, mountain adventures and shoulder-season trips. Built to keep you comfortable when temperatures drop well below freezing.
When you're camping in cold, damp conditions, synthetic insulation earns its place: OneThermo® holds its warmth in condensation and humid environments, dries fast and keeps its loft through frequent use. The body-contoured profile minimises dead air space, and a 3D hood, redesigned neck baffle, insulated zip baffle and insulated shark fin foot box trap heat and cut cold spots. The brushed lining is soft with excellent moisture transport. It weighs 1685g and packs to 36 x 24cm in the supplied compression sack.
