Since it's early beginnings as a contractor for the United States military, Alpha Industries has made it's name as purveyors of iconic, hard-working outerwear. While still rooted in American history and functional utility, the brand's aesthetic expression has evolved to be anything but old-fashioned. Case in point: the Insulated Shirt Jacket. Designed for a sleek streetwear aesthetic and crafted of down-filled, water resistant materials, the look is off-set by an invisible front zipper and barely-there front pockets that maintain a modern, minimalist vibe.
