Interior & Pocket Fabric

The plaid in the interior is a hollow yarn polyester brushed flannel. Hollow yarn makes the fabric light and traps air in the core of the fibers for greater insulation value. It looks and feels like your favorite flannel shirt but with performance features. The hollow yarn flannel also lines the hand pockets to keep your valuables, or your hands warm. 

Shell Fabric

All three colors are made from rugged performance fabrics. The Drifter and Deep Space Green (almost black) colors use a nylon/polyester twill fabric, while the Denim uses a brushed polyester denim. Both shell fabrics are waterproof, breathable and windproof yet retain a soft pliable hand. Their waterproof rating pressure test is 10,000mm. This is nearly 7x the minimum waterproof rating!

Polartec_ImageWe use Polartec Alpha insulation in our jackets. This redefining synthetic insulation was developed for people in extreme conditions and is used in some of the highest rated outdoor performance gear on the planet. Polartec Alpha is warm, breathable and very lightweight.

This breathable insulation allows for air exchange and works in tandem with the WPB shell fabric to keep you dry and comfortable in a wide range of temps and activity. You don’t have to climb mountains to wear this jacket, just know that the Polartec Alpha will keep you warm during the next Polar Vortex!


These are the actual garment dimensions. You should choose a size larger than your own exact measurements. As a general guide, keep in mind that this fit is smaller than Columbia Sportswear, but larger than Arc’teryx. Size exchanges available if in-stock.
