When winter's ending and spring's blooming, zip into the Arc'teryx Men's Kyanite LT Jacket and hit the trails. Its lightweight, stretchy fleece feels right when there's still frozen dew in the morning, and wicks moisture and dries quickly in case you get too warm. A Polygiene finish adds odor control for long-lasting freshness. Arc'teryx fitted it slim for easy layering, and articulated patterning ensures freedom of movement on the mountain.
