Description
The Robens Couloir 350 has been developed for situations where weight, volume and insulation make all the difference. The Box Wall construction guarantees an even distribution of feathers and prevents thermal bridges. With a comfort temperature of 2°C and a limit of -4°C, it is perfect for spring, summer and autumn, including more demanding environments at altitude.
Innovative centre zip for greater versatility
One of the highlights is the two-way YKK zip in the centre. It allows you to get in and out easily and also to use the sleeping bag partially open while sitting down - for example when cooking or resting. Thermal flaps on both sides and anti-jamming protection help prevent heat loss and increase comfort.
Ergonomic cut and optimised insulation
The body-fitting shape improves the warmth-to-weight ratio. The redesigned thermal collar and 3D hood effectively reduce the entry of cold air. The “shark fin” shaped foot area increases insulation in this sensitive area and gives more freedom of movement.
Light, compact and reliable for any adventure
At just 770g and with a reduced transport volume, it's easy to carry in your rucksack. The included compression sack allows you to reduce the size even further, while the mesh storage bag helps preserve the filling in the long term.
