The Robens Spire II is a synthetic mummy sleeping bag for three-season backpacking and camping, with a 2°C comfort rating and a -4°C limit. It's filled with Robens' OneThermo insulation and weighs 1,599g.
Built to hold heat. A body-contour shape, 3D hood and redesigned neck baffle cut down draughts, and a shark fin foot box adds extra insulation where feet get cold.
No cold spots at the zip. A full-length insulated baffle runs along the two-way YKK zip, with an anti-snag guard so it doesn't catch.
Thoughtful details. The hood cords are different thicknesses, so you can find the right one by feel in the dark. There's an inside pocket for valuables, and the brushed lining moves moisture away from you. It's PFAS-free.
Ideal for backpacking, wild camping, DofE expeditions and emergency kits.
