The Robens Spire III is a synthetic mummy sleeping bag for cold-weather camping, with a -3°C comfort rating and a -9°C limit. It's filled with Robens' OneThermo insulation and weighs 1,685g.
Warmth where you need it. The close-fitting body-contour shape means there's less air to warm up, and a 3D hood, neck baffle and shark fin foot box with extra insulation keep draughts out.
Draught-free zip. A full-length insulated baffle sits behind the two-way YKK zip, and an anti-snag guard stops it catching.
Easy to use in the dark. The hood cords vary in thickness, so you can tell them apart by feel.
Handy extras. There's an inside pocket for valuables, and the brushed lining moves moisture away from you. It's PFAS-free.
Ideal for winter camping, wild camping, DofE expeditions and emergency kits.
