A lightweight, long-sleeve shirt is warm-weather wardrobe essential. A classic flannel shirt in plaid and solid colors, our Lightweight Alaskan Guide Shirt is a perennial favorite. For a lightweight work shirt, chambray is a fabric that’s renowned for its durability and comfort. Designed for fishing, our Twin Lakes Sport Shirts are moisture-wicking and quick-drying. These lightweight button-up shirts are available with long or short sleeves. One advantage of a long-sleeve T-shirt such as our Barrier is the built-in flex that can be provided only by a knit fabric. That comfortable flex is a major reason why T-shirts are universal staples, and our Pioneer series are some of the finest available.
