Cliff is an automatised zipper developed for people who struggle to perform the zipping and unzipping task manually. Cliff uses two gear sprockets to provide traction on both sides of the tape, allowing the user to zip and unzip a garment with no hands. It was designed for the elderly as well as those suffering Parkinson's disease, but has the potential to offer relief to millions of women who struggle needlessly with garments that have zippers on the back.
