The 3-in-1 system jacket is the mother lode of outerwear. Comprising two independent jackets that fit together to form one supremely weather-resistant garment, these jackets are the ultimate in cold-weather comfort. That relentless commitment to performance often results in a list of technical specs as long as a 747 manual. But amid all the bullet-pointed terminology, the ease of wear and the simple attractiveness of these jackets might get overlooked. Don’t. These are all great-looking ambassadors for your clients’ imprint, absorbing all the lessons of retail-worthy apparel while repelling any wintry weapon thrown their way.
