The Men's Patagonia Sisar Down Vest provides versatile insulation before and after hikes and climbs. When you're up early at camp or around the fire post-adventure, the 600 fill power down packs a punch of heat straight to your core. The 100% recycled nylon ripstop shell is tough against abrasion and treated with a durable water repellent finish to deter light rain or snow as you sip on your coffee and get energized for the day's activities.
