This collaboration results in the strongest, lightest gear available that’s built for summit success.
RESPONSIBLE DOWN STANDARD
Certified to the Responsible Down Standard (RDS) by Control Union. The RDS ensures that our down does not come from animals that have been subject to any unnecessary harm, such as force-feeding or live-plucking, and helps track the down used in our products from farm to finished garment.
The fill power of goose down indicates two important features: the warmth-to-weight ratio and compressibility. Our products are insulated with exclusive, high-fill-power down ranging from 550 fill to 950 fill, representing the highest-quality down commercially available.
