A soft cotton canvas shell and polyester taffeta lining give the Clark Vest natural flexibility with a unique look and feel. Pillow-soft 120g polyester fill insulation keeps your core warm, while the vest design leaves your arms free to move without restriction. Wear it as an outerwear layer over your favorite woven flannel or tech fleece, for a dialed look that's perfect in mild mountain weather. Hand pockets add functional convenience, and the party pocket at the wearer's back-left is perfect for keeping a cold beer always within reach. It also works great for toting tools or gear—so whether it's work or play, you can show up prepared.
