Special Features

​PFC-free impregnation

This product has been coated with a fluorocarbon-free DWR-sealant (DWR = "durable water repellent"), in order to achieve a long-lasting, protective layer against oil, grease, dirt, and water.

Responsible Down Standard (RDS)

The Responsible Down Standard (RDS) aims to ensure that down and feathers come from animals that have had their nutritional, physical and emotional needs met. This means that force-feeding and live plucking is prohibited, and that the full supply chain is evaluated from the farm to the final product.

Do the job
Translated from the Swedish To the original
Ok, the advantage is that it is light in relation to what it delivers. Tested on 1 week in summer mountains and an autumn trip in the lowlands with down to 5 degrees in outdoor temperature. Have not frozen but also not been toasty warm. What I have to remark on: Personally of course but I think that the legs and toe box are a bit too warm in relation to the torso. I would have liked to have seen a little more loft over the chest and abdomen and a little less on the legs. Then it's the length, I'm about 176 and if you're taller than that and sleep on your back, then maybe you should consider an L. Finally, the straps to fasten around the mattress are too short if you sleep on a wide mattress. Have extended with rope cord but not sure if it is good for my mattress or not. However, this is not a problem if you sleep with the bag loosely on top of the sleeping pad
