Product Overview


The Super Down Ultra Jacket was designed for the hunter looking for an insulation layer with minimal weight penalty. This jacket should be in your pack on every hunt until the weather turns and more insulation is needed. With a mid-layer fit, the ULTRA jacket has room for base and additional mid layers, but fits snug enough so there is no bunching if worn under another jacket. We recommended to cover with a shell if traveling through thick vegetation. When not wearing the jacket, shove it into the left hand pocket which has a double sided zipper, enabling you to use the jackets own pocket for efficient storage.

Weighing a mere 6.4 oz, the warmth to weight ratio is incredibly high. Using a new finishing process for fabrics, we were able to take the original Super Down products and knock 40% off the total weight. This new process gave us the ability to use less down proof coating to create a lighter and more durable fabric. This new process in addition to a down proof coating make the fabric completely wind proof. We source all of our down from Poland, where the year long colder than average climate forces geese to generate lofty plumage to stay warm. The high quality 850+ fill power down is then treated with a DWR so that each individual cluster is impervious to water. This allows you, the end user to never have to worry about your down coat losing its loft when subject to moisture.

• 100% Nylon, 26 g/m² 12D ripstop fabric

Quixdown® by Toray

Waterproof Warmth 

Down has the highest warmth-to-weight ratio of any insulation material. The only drawback is that once wet, down stops being effective. Not anymore. Through nanotechnology, Toray Industries has created a water repellent finish for down feathers that makes each down cluster essentially waterproof. Quixdown® stays dry to keep you warmer with less weight and bulk.

Toray’s Kudos® XR DWR

Kudos® XR DWR (Durable Water-Repellent)

Kudos XR DWR performs better and lasts significantly longer than conventional DWR. DWR is critical for waterproof breathable face fabric. If DWR fails the face fabric “wets out” causing condensation build up on the inside of the garment.
