Mojo's Weather Buster soft-shell jacket combines features that will keep you well prepared to handle any chilly condition that comes your way. Mojo used advance materials that trap and retain body heat and also release excess heat. The result is a jacket that keeps you warm but not too warm. It is 100 percent polyester, wind- and water-resistant, and stretchy for ultimate comfort. The jacket also has zip-close side, chest and arm pockets, adjustable Velcro wrist cuffs and an elasticized draw cord for an adjustable hem.
