In a period when the worlds of menswear, high fashion, and sportswear have been intersecting and redefining each other, Mitchell & Ness‘s collaboration with Boylston Trading Company is a timely one. The Philadelphia-based sports heritage brand recently aided the online boutique with celebrating its one-year anniversary, creating a vintage baseball jersey as part of its “Coin & Leaf League” capsule collection. Crafted in the United States from authentic wool flannel, each jersey showcases “Boylston” embroidery across the chest with a “34″ on the back in navy blue felt. Elsewhere, four ventilation eyelets under each arm, a locker tag, and an assortment of patches on the garment’s sleeve and hem make for a nice combination of authentic vintage details and BTC’s contemporary touch. Available in extremely limited numbers, the Boylston Trading Company x Mitchell & Ness Vintage Baseball Jersey is available now at the retailer’s website.
