The GRIP4 looks like a full-fledged bite sleeve by its shape and included cap. This bite sleeve is designed specifically for use with or without a protection cap. This bite sleeve GRIP4 is the ideal way to go over to the bite sleeve experience or a Black IPO sleeve! Here you can also choose between a soft or hard sleeve. GRIP4 is recognisable by the black cap with the silver logo of JOSIE´S K9. If the protection cap is replaced by a right one, this sleeve can also be used by right-handers.
