If there's one thing you've gleaned from your outside adventures, it's that Mother Nature is predictably unpredictable. So the next time you head out for a slog up the skintrack or a bout on the trails, make sure you reach for the Arc'teryx Men's Adahy Hooded Fleece Jacket. Designed to combat the inclement nature of cool weather, the Adahy features a temperature-regulating fabric that wicks away moisture and dries quickly to assure ample comfort when the temperatures or conditions are in flux. Additionally, the fabric is inherently stretchy for unimpeded mobility, and the raglan sleeves are designed to prevent the hem from lifting and exposing your skin to the elements. Flatlock seams discourage hot spots and chafing, while the slim fit makes the Adahy ideal for next-to-skin wearing and therefore a suitable companion for high-output, stop-and-go adventures.
