lululemon Swiftly Tech Long Sleeve Shirt 2.0

This long-sleeve shirt is designed for running and training. But it’ll stand up to anything that gets you sweating, whether you lift, run, hike, or whatever else.

It’s made with lightweight, sweat-wicking material and has breathable mesh construction. The design has minimal seams to help prevent chafing. The shirt has a slim fit, falls at the hip, and incorporates thumbholes to keep sleeves from riding up during activity.
