Sometimes epic adventures take time to warm up. For those chilly starts, wear the Men's Calder Jacket. Thermal R® 40 gram insulation provides lightweight warmth that doesn't weigh you down. As the day and your adventure get going, its button-down style makes it easy to adjust to the weather. The PFC-free DWR (Durable Water-Repellent) finish protects you from unforeseen showers, while nylon fabric holds up to scuffs from the trail. Forward-set shoulder seams provide added comfort whether you're traveling with or without a backpack.
