This 3-in-1 wonder from Columbia defies cold and wet weather. An insulated inner jacket features advanced thermal-reflective lining while the outer jacket has waterproof-breathable technology. The Zip-in Interchange System lets you wear as a shell, a liner or zipped together for full protection. Omni-Tech™ critical seam sealed technology prevents moisture from seeping into essential areas using waterproof fabric, so you stay dry in the rain. The Omni-Heat™ Infinity lining retains body heat using an expanded pattern of thermal-reflective gold dots to keep you extra warm in cold conditions. Plus, the adjustable hem and cuffs seal out the elements.
