If you plan to encounter some colder temperatures with your quilt, you may want to add the optional Gryphon Gear custom collar (patent pending). The collar is like putting an adjustable turtleneck on the quilt. It can be left loose or snugged up around your neck to eliminate drafts. The draw cord is on the inside of the quilt putting it within easy reach. Putting the draw cord on the inside also allows the insulation to maintain its maximum thickness in this area.
