With the integrated feel of a single jacket and the convenience of a 3-in-1, the Columbia Cushman Crest Interchange Jacket is your go-to throughout the season in one way or another. Wear the shell alone for its Omni-Tech membrane's protection against wind and water, or choose just the liner for its synthetic insulation blocking out the chill, either is a perfectly functional jacket on its own. Option three--integrating the two--gives you the warmth and protection without feeling like you're layering up.
