Black Diamond Men's Coefficient 1/4 Zip
The Black Diamond Men's Coefficient 1/4 Zip top is an essential layer for mountaineering and alpine ascents, using Polartec Power Dry High Efficiency fleece for versatile mid weight insulation and extreme breathability. The gridded interior increases moisture transport to dry quickly during high-output activities or after unexpected showers. Features Polartec Power Dry High Efficiency fleece Brushed microsuede collar lining Zippered chest pocket Stretch cuffs Glossary Polartec Power Dry High Efficiency Created to push the performance of our base fabric technologies even further. By developing a patented grid design structure we discovered a new way to reduce fabric weight while increasing warmth and compressibility in the process. This grid construction enhances both wicking efficiency and breathability by generating channels of targeted touch points that absorb and diffuse moisture vapour for faster evaporation.
