For active days when the temperatures drop, we love a good, thick long sleeve tee. Add a little hit of rad 90s style with a chest patch? Even better. The Swallowtail Long Sleeve T-Shirt offers a thick, shrunken fit that adds warmth without adding bulk. It's simple, timeless, and its soft cotton baby rib fabric is treated with a premium garment wash so it feels naturally lived-in from the first wear.
