Long Sleeve Level Tee

Black
Grey

Our most technical tee, the Level is engineered to provide top performance through the toughest conditions (and it makes great travel wear, according to Men’s Journal). The secret? 37.5® technology, which uses active particles to vent heat in warm conditions and retain it if it’s cold. This tech is proven to increase your body’s efficiency by up to 26% at lactate threshold, so you can push yourself further than you’ve ever gone before.

Fabric

The 37.5® technology in the Level Tee sets it apart from every other shirt in your drawer. In hot temperatures, active particles embedded in the fabric release heat energy and help sweat evaporate more quickly off your body. When it’s cold, the particles trap heat energy to keep you warm. That means you waste less energy regulating your temperature and have more energy to put into your workout.
