DESCRIPTION: The Grumman Down Jacket delivers exceptional packability, warmth, and protection for the backcountry hunter in a truly ultralight package. Built with a Pertex® Quantum shell and insulated with HyperDRY® 850+ Fill Power DWR-treated goose down, it remains one of the lightest and most technically advanced down hunting jackets available. This updated version features a refined face fabric using a dull yarn and a micro-ripstop construction for improved durability and a quieter, matte finish in the field. Pocket depth has been increased by 2 for enhanced comfort and usability, and a built-in containment pocket allows the jacket to compress into itself for easy packability. Subtle fit adjustments improve overall comfort and layering performance, while a well-fitting hood, reverse-coil YKK® zippers, and a unique cuff design complete this proven insulation piece.

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. Measured Chest: With arms relaxed at your sides, measure under your arms, around the fullest part of your chest. 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. Measured Belt Line: Measure around your waist at the point in which your pants typically ride. 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.
