Runzie, The Ultimate Bib Number Holder, is a unique belt designed to hold the bib number placard for those participating in runs and other activities. It securely holds the bib number in place, thus eliminating the need for safety pins. The holder is made of lightweight nylon with a front portion made of clear vinyl which is opened at the top to allow the bib number to easily slide into place. The bib number can be clearly seen and unobstructed while also being protected from the environment. The nylon strap is adjustable and fastens with a plastic clip closure. There is a zippered pocket at the top to securely hold small items including cell phones and energy gels. Another version, Runzie Muff, includes a hand warmer muff. There is an opening behind the clear vinyl pocket which is lined with a fleece-like material. The muff allows individuals to place their hands inside for warmth on those chilly days. The zippered pocket is still available to hold small items.
