Long sleeved t-shirts are a staple of every guy's tee shirt wardrobe. Whether for vigorous workouts or couch surfing, there are long sleeve tee styles for everyone. Outdoor athletes will appreciate high-tech compression tees and those specifically designed to keep body heat in and cold weather out. For those who train in cold weather, moisture-wicking long sleeve tees are a great base layer, keeping you dry. Thermal knit t-shirts, often made of cotton or a cotton blend, work as PJ tops as well as great loungewear or an extra layer in the cold. For luxurious comfort, there are 100% mercerized cotton t-shirts that come with long sleeves. Loose fit shirts are great for hanging out and leisure days. If you want to add a little style to your tee shirt collection, consider color block tees, shirts with contrast piping or form-fitting cut to show off that gym-fit body. For cold-weather outdoor sports, a mock turtleneck design that fits close around the neck will keep heat in, for a warmer workout. And, of course, everyone needs that old stand-by, a comfortable fleece crew neck, soft and cozy any time.
