S-Lab is Salomon's high-performance line, and the S-Lab Exo Men's Short Tight lives up to the billing. Using a combination of ActiLite Pro stretch-woven fabrics, the Exo has a Sensifit compressive fit that's been shown to support muscles and improve posture, helping you run faster, go longer, and recover more quickly. For ideal comfort, the Exo uses SmartSkin body mapping, which places compressive fabrics where support's most important and mesh panels where breathability should be increased, and incorporates a Cocona internal brief that wicks moisture, fights odor, and dries quickly. It also has a plethora of gel pockets and reflective details, so you won't bonk or get bonked by a car when you're putting in long road miles early in the morning.
