The best thing about the Columbia BUGABOO II FLEECE INTERCHANGE JACKET 3 v 1 is that you can wear it from spring through winter. It is designed to allow you to add and remove extra layers of insulation depending on the weather. On chilly days, you can add a layer of fleece lining, which doubles as a separate top layer for warmer days. When the fleece lining is removed, the jacket’s insulation is taken care of by the built-in layer of warm thermal-reflective lining. Shell with Omni-Tech® membrane ensures waterproofness and breathability. Adjustable cuffs, lower hem, and hood together with the Outgrown™ system ensure perfect fit across multiple seasons.
