A strong case for wearing Japanese indigo into colder temperatures, the Reinforced Thermal Jacket is a masterful way to flip the script on layering with a jacket that's really two in one. Sourced from Japan, unwashed heavy indigo is crafted to wear and age beautifully, acquiring patina and lending structure season after season. Our indigo stripe is specially woven from fly shuttle looms that have been in use for more than a century, carrying this storied technique into the modern day. A thermal waffle lining adds warmth without the cumbersome bulk of overzealous layering and plenty of thoughtful details (knit rib cuffs and waistband, an elastic drawstring hood, and a center front-zip closure) provide insurance against most unforeseen conditions.
