Black Diamond CoEfficient Jacket -

The Black Diamond CoEfficient Jacket offers a lot of versatility in a minimalist package. The Polartec Power Dry High Efficiency fabric is light and stretchy to give you the mobility required to tackle some rigorous outdoor pursuits, like scrambling around a summit or running from a marmot. If you ever do find yourself being chased by a marmot just remember this one thing: stop running, it's just a marmot. The CoEfficient is warm enough to be worn on its own during the transition months or can easily be layered under a shell to take on extreme conditions. This jacket can help you out in a lot of ways, but unfortunately can't do anything about your irrational fear of cute, fuzzy animals.

Calling the Black Diamond Men's CoEfficient Fleece Jacket a versatile mid-layer might be an understatement considering the fact that you take it out on every cold-weather excursion. Its high-range versatility is due to the unique Polartec Power Dry High Efficiency fleece fabric that covers your body with soft warmth. Not only does it warm you, it's remarkably breathable and dries fast so you stay comfortable while you hike up powder-capped peaks or pick up a sweat during climbing expeditions whether they're long alpine ascents in the Tetons or short sport routes late in fall. And it's especially durable to withstand all the beatings you inflict on it all year long.
A slim fit pulls the CoEfficient close to your body to both help you layer up for ski sessions and reduce bulk to your climbing attire. Stretchy cuffs feel soft on your wrists, and Black Diamond lined the neck with cozy chamois for additional comfort. One chest pocket is all you need for your phone and wallet while you climb up some peaks or drop down them.

Positive Reviews:

The Coefficient fit is a little slim. I like the little details like the Chamois-lined neck (super soft) and the stretchy cuffs. The arms are long enough that I can pull the stretchy cuffs pretty far down and give my hands some warmth when needed. Polartec Power Dry works great as a layering piece (especially with the slim cuffs) but I have used mine mostly for climbing and high aerobic outer layer.

Neutral Reviews:

I've used this as a mid layer or under a ski jacket about 6 times. It has a slim fit and has enough sleeve length for my long arms. However after only using it that small amount of time the material is pilling on the forearms and shoulders so it looks old and well worn very quickly. I have the orange if it makes a difference.
