Comfortable and stylish shorts infused with advanced temperature-regulating fibers

At first glance, the Caldera Shorts look like the casual, comfortable, crossover shorts that they are. But they’ve got an ace up their sleeve in a little yarn called 37.5®. It’s a technical fiber that’s specially designed to maintain your body’s core temp and manage the relative humidity in the air between your skin and the fabric, keeping both at the ideal 37.5°C. No matter the weather, the activity, or the temperature, these shorts can keep you comfortable, from lounging on the couch to pushing your PR at the track.


  • Made from a soft four-way stretch material infused with 37.5® fibers
  • 37.5® fibers regulate warmth and keep your body at a comfortable temperature
  • Elastic waistband with an adjustable drawstring for the perfect fit
  • Side seam hand pockets with a single zippered rear pocket
  • Tailored fit for a clean look
  • 70% polyester with 37.5® fibers, 24% rayon, 6% spandex
  • The Caldera Shorts have a clean, tailored fit that's not too tight, but not too baggy
  • We recommend taking your normal size in athletic shorts, but if you prefer a more relaxed fit then consider going up a size
