Always be prepared for unexpected weather shifts with the Hideaway Jacket. Made of ripstop waterproof nylon, this windbreaker is so small; it’ll fit anywhere–purse, bike jersey, glove box. But here’s the secret weapon–the Hideaway Jacket has strategically placed panels built into its design that can be used for any type of insulation: dry leaves, newspaper, cotton. It instantly transforms from a compact windbreaker to a warm puffy coat.
