When the changing seasons blow in perfectly crisp friction weather, we button into the Black Diamond Project Flannel and plan the weekend's climbing trip. The brushed cotton material heats and breathes, while its organic origin saves water and energy in production to lower our carbon footprint. Constructed with an updated fit, this layer lets us move freely on warm-up problems and when post-send lounging.
