When sub-freezing alpine starts give way to sun-baked afternoons of ridge traversing, the light and dynamic Black Diamond CoEfficient Jacket’s slim, full-zip construction helps manage temperature and moisture to keep layer-swapping to a minimum. Featuring a stretchy and highly breathable Polartec PowerDry High Efficiency fabric that is unique to Black Diamond, the CoEfficient Jacket balances insulating warmth with efficient heat regulation for the high-output, stop-and-go nature of alpinism.

    I've heard this jacket runs a little small. Have you found this to be true?

      Absolutely, yes. The whole Black Diamond line is intentionally a slim, athletic fit -- like some of the European brands. It's a great fit, honestly, it layers well and is long enough that you're not exposing skin if you are climbing or lifting your arms above your head. I'd plan to order one size larger than normal. For example, I wear a size medium in most brands, but I sized up to a large for the CoEfficient jacket.
