Tommy JohnEverything from Tommy John is made with the 3 F's in mind: fabric, fit, and function. Ultimately, that means you get high-quality, innovative fabrics that are supremely comfortable. Tommy John is on the pricier side, but we think it's worth every penny. If you want something lightweight, this set will be your go-to. The material is stretchy, swingy, and soft, making it comfy to lounge in for hours. If you want something a bit heavier, Tommy John has plenty of sweatpant sets too.
