The pinnacle of warmth

Advanced thermal performance in extreme conditions.

About the technology.

Cloud Down uses a discontinuous offset baffle construction for optimal thermal performance in frigid environments.  

Our unique design features an asymmetrical inner and outer construction, allowing maximum space for the down to loft while keeping the lining close to the skin for enhanced thermal protection.

The outer and inner liners are welded together, and the absence of stitches eliminates the presence of cold spots for maximum comfort.

Due to the minimal amount of fabric used in the construction, Cloud Down is exceptionally compressible and can be packed into small spaces for extra warmth when needed.

We only use Responsible Down Standard (RDS) filling to ensure our down is ethically sourced, responsibly produced and traceable.

The use of natural down in our Cloud Down technology ensures it delivers the highest warmth-to-weight ratio of any insulation.

How to layer
Cloud Down is worn on top of an outer shell, as additional warm insulation in dry conditions during a belay or in basecamp.
