Grumman LITE Down Jacket
Ultralight and packable down insulation worn as an outer layer during static activity in cool conditions or layered underneath a shell in cool, wet conditions.
The Grumman Down 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 Jacket provides the exact same functionality as the original Grumman but in a minimalist design made for milder conditions.

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.
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 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.
- Unfasten the top buckle attachment and unzip the zipper fly.
- While the zipper fly is unzipped, detach the left side (left as when the wearer is looking down on the zipper fly) of the zipper from the hook and loop pad by pulling it down and away, starting at the top.
- Reattach the zipper fly to the hook and loop pad by starting at the bottom and pressing it firmly and evenly up towards the top. Attaching the zipper at a steeper angle to the left, will adjust the pants smaller. Attaching the zipper further to the right will adjust the pants larger.
- Once the zipper is reattached, zip up the fly as normal and fasten the top buckle, adjusting tension as necessary. Repeat steps 3 & 4 until the proper fit is achieved.
- Once you find your proper fit the zipper fly will work as normal and adjustment does not need to be made again until required when layering or as desired.
