Functional. Transitional. Formidable. It starts with a sturdy cut of windproof cotton. Then it's beefed up with a warm quilted lining. Pity the wind that tries to penetrate the Reinforced Riding Shirt Jacket. Function is up'ed with an abrasion-resistant sleeve and back lining as well as body armor pockets. This layer walks the line between casual jacket and functional gear. Features a Slim Fit that is narrower throughout. Like it roomier? Size up.
