Men's Stone Glacier Grumman Lite Down Gianna jacket

18284-20010-MK

The Grumman Down Gianna jacket has been a staple in our packs since its inception, but we often found that it was just more insulation than we needed for most early season conditions. Enter the Grumman LITE. Ultralight yet packed with 850+ fill HyperDry goose down and a weather-resistant face fabric, the Grumman LITE Down Gianna jacket provides the exact same functionality as the original Grumman but in a minimalist design made for Heart conditions.

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 that 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.
