A ShirtJac is a versatile combo of a shirt and jacket. Shirt Jacs or Lined Shirts make an excellent work shirt and layering piece. For a truly heritage feel and timeless look, dive in to our 7.4oz 100% cotton Moleskin Shirtjac. This heavy cotton fabric is woven and then sheared to create a short soft pile on one side. Outstandingly comfortable, stylish and plays well with anything in your wardrobe. The feel and appearance of its texture is similar to chamois, but less plush than velour.
