Calor 1/4 zip Large Approach

When we first started playing around with Heatwave™ technology we knew our first product had to be a 1/4-zip base layer. When you wear the Calor 1/4-Zip next to your skin, the Heatwave technology is activated, giving you those extra degrees of warmth that can be the difference between a miserable hunt and a memorable one. When you need one, the Calor 1/4-Zip makes a great mid layer, too.
