The Black Diamond CoEfficient Hoody has become my go-to layer for just about everything from technical pursuits to just plain hanging out. The last time a piece of technical clothing worked its way into my everyday life as deeply as this fleece was my old Patagonia Puffball vest, which I still wear. Though Black Diamond has dabbled in clothing over the years, the CoEfficient fleece hoody is part of a new and more comprehensive technical apparel line launched this year.
What’s so great about another fleece hoody, you ask? First, it’s not just any fleece; it’s Polartec Power Dry High Efficiency fleece. It’s got the waffle back and smooth face, breathes incredibly well and serves up a remarkable warmth to weight ratio. The fabric weight is similar to a Patagonia R1, maybe a touch lighter. Next, it’s truly a technical piece. It’s cut long to work with harnesses and under shells. The fit is athletic and simple features like stretch cuffs and a scuba style under-the-helmet hood design really add to its functionality. The full-length zip makes for easy on and off and, when fully zipped, offers great neck, chin and cheek coverage. I’ve taken it skiing, climbing, pedaling and hanging out from sea to summit.
Black Diamond nailed the cut, features and weight on this one.
