The Grumman Goose Down Jacket brings the ultimate in packability, warmth, and protection to the backcountry hunter. We set out to design a piece that truly met our definition of “Ultralight.” The combination of a Pertex® Quantum shell with HyperDRY™ 850+ Fill Power DWR treated down makes this a highly technical insulation piece unlike any other in the hunting industry. Weighing only 11.8 oz. with 5.3 oz. of 90/10 goose down fill, you will be hard pressed to find another down jacket with comparable stats. A well fit hood, reverse coil YKK zippers, and a unique cuff design paired with strategic color blocking for breaking up body symmetry on the mountain have made this piece an office favorite at Stone Glacier.
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.
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 below.
PROPER FIT & USE:
Our patented Contour Waist™ System is designed to provide an exact fit around your waist. No more buying pants that are slightly too large or don’t fit quite right. As well, this system allows you to adjust the waist size of your pants to allow for a proper fit when layering base layers or insulation bottoms underneath. To adjust the Contour Waist, follow the below steps:
Note: Proper fit is best achieved by adjusting the Contour Waist while wearing the pants.
The Stone Glacier Grumman Goose Down Jacket is an iconic "puffy" jacket that is both ultralight and incredibly warm. It's perfect for those sedentary moments in the field such as glassing or in camp. It also fits well in the stuff sack that's provided and with minimal effort.
