The same, patented jacket-to-pant connection that Volcom uses throughout their line of adult snow gear. Strategically placed zippers on the waist of Volcom pants, as well as the powerderskirt of most jackets, easily zip together. This zippered feature creates an excellent barrier that not only keeps your pants up and your jacket down, but keeps the majority of snow and wind out of your outerwear, giving you similar protection to what you would get with a one piece snowsuit. The Zip-Tech™ system is designed to work only with Volcom jackets and pants.
