Keep your muscles supported on longer runs with the Salomon S/Lab Exo Half Tight. This half tight was designed with compression and support where you need it most, using a body-mapped construction to help deliver quick muscle recovery and mid-run performance for long excursions on the road or trail. The fabric is lightweight and quick-drying to keep you comfortable as you sweat, and features a special zone of mesh that uses 37. 5 fabric technology. 37. 5 technology works to keep your body at an ideal temperature of 37. 5 degrees Celsius while maintaining 37. 5% humidity next-to-skin. Both the temperature and humidity levels are ideal for maximum performance--not too hot and not too cold, ensuring a comfortable run no matter the temperature. That's not all there is to love about this tight, though. It's also compatible with Salomon's S/Lab belt--a stretchy, lightweight belt that can quickly clip into the front attachment point of your shorts, giving you extra storage for energy gels, packable layers, keys, and cards. The four-way stretch fabric helps you move freely and comfortably throughout your whole run, while UPF 50 sun protection shields your skin on sunny summer trail runs.
