No matter whether we are biking, hiking, running, or training, having a performance base layer that optimizes our comfort both on its own and when combined with layers is a staple in our gear closets. The District Vision Lightweight Long-Sleeve T-Shirt is one of our favorite performance tees due to its lightweight and technical fabric that keeps us comfortable when we are performing our best. The stretchy nylon blend moves with us, wicks moisture from our bodies, and dries quickly so we can focus on our workout, not what we wear.
