Stone Glacier - Drumlin Heavy Down Jacket

DESCRIPTION:

Built for the ultra-cold days when maximum warmth is essential. The Drumlin features an innovative overlapping baffle design that eliminates cold spots and creates a continuous R-value across the entire jacket.

High-loft insulation is strategically mapped to retain heat, while the durable outer shell cuts wind and resists moisture. Whether you're glassing long hours in subzero temps or just braving the coldest conditions, the Drumlin is your ultimate barrier against the elements.

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.

Responsible Down Standard (RDS)
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.

Stone Glacier products are designed with an athletic fit to provide the highest level of performance in the field. Use the sizing chart below to help guide you to the appropriately sized garment. Note, the De Havilland Pants incorporate our patented Contour™ Waist System which provides approximately 3 inches of waist adjustment to create an exact fit.

How to Find Your Measurements:

Note: Calculate your body measurements, then select your product size. If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.

1. Measured Chest: With arms relaxed at your sides, measure under your arms, around the fullest part of your chest.
2. Measured Sleeve: With arm relaxed at your side and slightly bent, measure from center back neck, across the shoulder to elbow and down to the wrist.
3. Measured Belt Line: Measure around your waist at the point in which your pants typically ride.
4. Measured Inseam: From a standing position, measure from your crotch down the inside leg to the floor.

Nearly all Stone Glacier pants feature our patented Contour Waist™ system, which allows for three inches of waist adjustment. Additionally, SG pants are sized accordingly for layering. If you wear a large in our base layers, you will also wear a large in other SG layers. If you are still unsure of what size pants to buy, measure your waist and reference the "Measured Belt Line" chart above.
