Carhartt WIP reinvents the timeless MA-2 bomber, a military-inspired style that has outlived countless fashion trends. The Olten is a modern reinterpretation, made from water-repellent nylon twill and lined with nylon taffeta. It maintains all the iconic utility-focused design elements, including a cinched rib knit hem and cuffs, along with a handy zipped pocket on the sleeve.
