From mild drafts to an unpredicted storm, the Men's Drake Passage Featherless Component Jacket is a 3-in-1 jacket that will keep you warm no matter what Mother Nature throws your way. Waterproof, breathable, and windproof Marmot MemBrain® fabric and 3M™ Thinsulate™ featherless insulation will keep you warm without weighing you down. Critical seam taping and a storm flap help keep out the rain. Stash keys, phones, and other small gear in the chest and hand pockets. If a balmier day is on the horizon, the interior zip-out vest can be worn separately for just the right amount of protection.
