Technology
Pertex® Quantum uses a tightly woven structure to provide a light and soft fabric that allows insulation to fully loft while also being quiet, windproof, lightweight and packable.

Pertex® Y Fuse fabrics use yarns with unique Y shaped filaments. These filaments create a tightly interlocking structure which improves downproof and water beading properties. The interlocking structure of Y Fuse fabrics remains highly stable over extended wash and wear cycles

Super DWR is a water repellent finish that maintains its high performance through extended wash and wear cycles

HyperDRY™ water-resistant down is treated with a unique fluorocarbon-free treatment that adheres to the down cluster and allows down to retain its superior warmth to weight ratio — even when wet.

All down products from Stone Glacier come from an RDS Certified Supplier. We only use down that comes from ducks & geese that were treated ethically.
