The Pack Windbreaker is beyond a clothing item- this piece of equipment separates the tourist from the adventurer with each of its 19 pockets. The elements can bring wind and rain to even the most temperate climates, but you can be prepared without having to give up precious carry on space for a jacket. Instead the Pack Windbreaker IS a carry on with its Weight Management System, Personal Area Network and pockets for your tablet, point and shoot camera, eyeglasses and much, much more. The Pack Windbreaker is treated for water and stain resistance, and the back pocket inverts to store the jacket when not in use.
