The Icon Insulated Denim Pant. The Icon design and development team is located in dark and cold Portland, Oregon. Most of them ride to work year round. Those of you who do the same will understand what they're up to with this genius product. The big deal here is the removable and washable insulated lining, which gives you the choice of ultra toasty or cool and loose. The outer chassis is heavy 14 oz. denim with integrated Aramid reinforced knee and hip panels all blended together with some trick urban styling. We can't warm your tires before you set out, but Icon can offer a product that keeps your knees from knocking against the tank.
