You can take the Columbia Women's Whirlibird Interchange Jacket out on chilly shoulder season hikes as well as winter ski sessions. Zip out the insulated liner when you only need this jacket's Omni Tech waterproof protection for rainy summer strolls, and zip the liner back in when it gets cold out. The liner's Omni Tech thermal reflective lining uses silver dots to reflect your body heat back to you. The liner is also water resistant to shed rainfall on autumn camping trips. An active fit makes sure you can move freely in the Whirlibird, and a drop tail hem enhances your coverage from the wet world. The Whirlibird also features a powder skirt that snaps back when not in use, a removable hood, and adjustable cuffs for a secure fit.
