The system safely attaches to a helmet without any modifications to the helmet and therefore does not impact the warranty or safety rating of the helmet. The helmet cover is designed to stretch and conform to numerous different helmet styles and manufacturers, while serving as an attachment point for the pliable retainer. The pliable retainer provides the tensile force necessary to keep the chin protector in place throughout the range of movement common during sporting activities, as well as during an impact to the chin. The chin protection system may be utilized on any safety helmet including, but not limited to, bike helmets, skateboard helmets, rollerblade helmets, ski/snowboard helmets, motorcycle helmets, go-cart helmets, baseball and softball helmets, and climbing helmets. ## Claims ### Claim 1 A chin protection system for releasable attachment to a helmet (100) with a helmet shell (110) and a helmet ledge
