Frequently Asked Questions
We recommend using a specialized down detergent and a front-loading washer on a gentle cycle. Tumble dry on low heat with tennis balls to ensure the down is fully lofted and clump-free.
The nylon shell is water-resistant, meaning it protects against light rain, dew, and damp ground. For heavy precipitation, we strongly recommend using the sleeping bag inside a tent or with a waterproof bivy sack.
The mummy design contours to the body, reducing the amount of cold air trapped inside. This allows the duck down to heat the smaller space more efficiently, providing superior warmth in extreme cold.
Yes. The two-way zipper allows you to open the bag partially or fully, effectively turning it into a quilt or blanket for ventilation during warmer summer nights.
Downproof technology refers to a specialized weave and treatment of the fabric that prevents the tiny duck down feathers from leaking through the shell, ensuring the insulation stays where it belongs.
With a rating down to -15°C, it is excellent for most high-altitude camping and winter trekking. For professional expeditions in sub-zero arctic conditions, we suggest pairing it with a thermal liner.
