Our Taurus Bags now come standard with our Gryphon Gear custom collar (patent pending). The collar is like putting an adjustable turtleneck on the bag. It can be left loose or snugged up around your neck to eliminate drafts. The draw cord is on the inside of the bag putting it within easy reach. Putting the draw cord on the inside also allows the insulation to maintain its maximum thickness in this area. The accompanying picture shows the collar on our Taurus VRB™ Bag.
