Abstract: A material winder is used winding long, loose straps of material, such as handwraps used in boxing. Often, long, loose straps of material are awkward to store and may look unkempt if stored unwound. The material winder provides a compact and portable device for quickly and conveniently rolling up long strips of material into tight rolls for easy storage and use. The material winder may include a handle having a material guide attached thereto. A winder core may receive material through the material guide. The winder core may be rotated to wind material about the winder core while the material guide ensures the material winds in an even roll.
