The Illusion Jacket is a year round travel essential and a pretty cool addition to your daily wardrobe too. This insanely lightweight jacket weighs only 2 ounces and is still wind and water resistant. And, it stuffs into it's own pocket so you can carry it in your purse or backpack everyday, everywhere - just in case! Wear it tied at the waist for a sheer blouse look. It's indispensible!
