Robens Couloir 350 -4°C Regular Sleeping Bag - 700 FP Down (770g)

The Robens Couloir 350 -4°C Regular is a three-season down sleeping bag with 330g of 700 fill power duck down, a 2°C comfort rating and a centre zip, in a Regular fit with a 180cm body length. At 770g and packing to 24 x 15cm, it's built for backpacking, trekking and bikepacking where every gram counts.

The centre zip is what sets the Couloir apart: getting in and out is simple, and you can sit up with the bag part-open for a brew or to sort kit. Inside, responsibly sourced and traceable 95/5 duck down sits in box-wall construction so the loft stays even. A 3D hood, a redesigned neck baffle and a double-sided zip baffle work together to shut out draughts, and the shark fin foot box gives your feet room and warmth. Ratings run from a 2°C comfort through a -4°C limit to a -21°C extreme.
