37.5 Active Particle Technology

You work hard and you need gear that can keep you going. That's why at Vertx® we strive to incorporate the best performance technology into our apparel. Our partnership with 37.5® Active Particle Technology started 10 years ago with our Integrity Shell Jacket and now encompasses a full line of shirts, pants, and accessories. In any condition, 37.5® fabrics are working with your natural microclimate to keep you performing at your peak, longer. By capturing your natural infrared (IR) energy, 37.5® can evaporate moisture to keep you cool or reflect it back to you to keep you warm so, you can stay comfortable no matter the weather or activity.
