Shoulder pads use a shoulder and chest measurement for customers to use in the selection of the correct size for a player. Kato Collar will fit in all shoulder pads sized large or larger and will fit in any shoulder pad which measures 9 ½” in diameter across from the plastic component which forms the opening for the neck. Kato Collar is designed to fit with velcro, although has been worn in shoulder pads sized large and above when shoulder pads are properly fitted, and the jersey is designed to fit tight holding shoulder pads in place and preventing migration of the shoulder pads.

Most shoulder pads now have hook velcro sewed into the underlining of the pad to allow for attachment of channel pads. Kato Collar’s design of the flange with loop velcro on the top o the flange and hook Velcro on the bottom of flange allows it to attach with all shoulder pads with hook velcro sewed into the underlining of the pad. The hook velcro on the bottom of flange allows for the channel pads to be reapplied after Kato Collar is in place.

We offer different sized deceleration pads to allow for varying neck lengths. Please contact our sales team at for specifics on the deceleration pads and other sizing questions. Here is a sizing chart for reference.
