Zip Tech® Jacket to Pant Interface – Whether waist deep in the backcountry or trying to one-up yourself in the park, nothing lowers motivation faster than snow jammed down your pants and up the back of your jacket. Volcom has officially patented Zip Tech®, their originally designed and heavily imitated jacket-to-pant interface that allows you to zip the powder skirt of virtually any Volcom jacket to any Volcom pant, keeping snow out and heat in with no restriction of movement. Falling has never been more enjoyable
