Robens Scoria UL -6°C Long Sleeping Bag - Ultralight 850 FP Down

The Robens Scoria UL -6°C Long is an ultralight down sleeping bag with 445g of 850 fill power RDS-certified duck down, a 0°C comfort rating and a -6°C limit, weighing 820g in the Long fit. For cold-weather camps and shoulder-season and winter trips where you refuse to carry a heavy bag. The weight saving comes from smart design rather than skimping. The 90/10 duck down is split 60% top / 40% bottom, so the insulation sits where it works instead of being crushed beneath you, and H-box construction with a differential cut keeps the loft even. A 3D-shaped hood, overstuffed draught collar and shark fin foot box look after your head and feet, while the comfort mummy shape leaves room to move. The hood drawcords are differentiated by thickness and structure so you can adjust them by touch in the dark, and the YKK two-way zip has an anti-snag cover. Inside there are drawstrings for adjustment and a pocket for small items; outside, hang loops make airing simple. Packed size is 33 x 17cm.
