Product Info

Alpine touring can be a temperature nightmare. Sub-freezing temps and alpine starts can quickly turn to scorchers that have you shedding layers like an onion. The Black Diamond CoEfficient Jacket will help you manage temperature and moisture thanks to it's full-zip construction and highly breathable Polartec® PowerDry® High Efficiency Fleece, striking the perfect balance between insulating warmth and heat regulation.

Product Details


Polartec® PowerDry® High Efficiency Fleece207 g/m², 88% Polyester // 12% Elastane: Polartec® Power Dry® High Efficiency™ fabrics are designed to keep your skin dry when you sweat. All fabrics in this series feature a bi-component knit construction that uses different yarns on either side of the fabric. This creates two different surfaces: one that is optimized to move moisture away from the skin, the other to dry quickly.


Slim FitA slim, body-hugging fit that makes it an ideal addition to your alpine layering system while providing quick drying insulation without weighing you down.
