What does "Calor" mean, you ask? Heat, love, passion...all things you’ll experience with the Calor Pants. We coupled a durable softshell with Badlands' Heatwave™ technology, so it reacts with your own body heat to give you a few extra degrees of warmth when you need them most. You'll also appreciate the reinforced knees, reinforced hems, double-belt loops, cargo pockets, and side zips which make the Calor Pants even more functional. Oooh, we can already smell the passion.
