Fabric Tech Info

We sew our Jackets, Vests & Hats using engineered fabrics which offer a combination of weather protection, durability, comfort and breathability.

These Hi-Tech laminated fabrics include 2 types:  Softshell fabric and Windblock Fleece. When viewing our products, you'll also see a 3rd fabric description called "Hybrid", which indicates that item is a combination of Softshell fabric & Windblock Fleece. 

Our Hi-Tech Fabrics employ a strategic system of layers, with 2 different fabrics (the interior and exterior layers) bonded together by a hidden 3rd layer; the weather-resistant membrane.  Sandwiched between the inner and outer layers of fabric, this highly water-resistant/breathable membrane is the key player.  In Softshell fabrics, this membrane is engineered to block 98% of the wind, while still allowing 2% of air to pass through for ventilation.  In Windblock Fleece fabrics, the membrane provides a 100% windproof barrier for maximum warmth.  

In addition, the outer-faces of both Softshells and Windblock Fleece fabrics are treated with DWR (durable water-repellant finish) to help shed rain & snow.  

Windblock Fleece Fleece outer-face bonded to a fleece inner-face 100% Windproof  Laminated membrane creates an H2O-resistant barrier, while still allowing moisture vapor to escape DWR (water-repellant surface treatment) applied to outer-face sheds rain & snow Provides superior warmth without weight or bulk 2-way stretch enhances mobility Outstanding durability Moisture-wicking interior Machine-washable

 Our Softshell and Windblock Fleece fabrics are highly water-resistant and do an amazing job keeping you warm and dry, although in a downpour they are not completely waterproof.  But keep in mind, Copper River Fleece's hometown of Cordova, Alaska is right in the middle of a coastal rainforest, and throughout our 25 years in business, staying warm & dry is something we've specialized in!
