The Robens Spire II -4°C Sleeping Bag is a synthetic mummy bag with OneThermo® insulation, a 2°C comfort rating and a -4°C limit, for campers, backpackers and trekkers who need a bit more warmth when the temperature starts to drop. It covers spring, autumn and mild winter conditions.
This is the Spire for cooler three-season nights. OneThermo® synthetic insulation keeps insulating in humid and wet conditions, dries quickly and holds its loft through regular use. The body-contoured shape is heat-efficient, and a 3D hood, redesigned neck baffle, insulated zip baffle and shark fin foot box work together to minimise heat loss where you feel it most. The brushed lining is soft and moves moisture away from your skin. It weighs 1599g and packs to 33 x 23cm in the supplied compression sack.
