I remember in the early 2000's the unicorn chest protector from RBK, the pro spec p1 which was based off the previous Koho 590 unit. They couldn't be ordered from a store, the only way was pro returns from the various pro/semi pro and Jr hockey leagues ( same now as the CCM pro unit) . Because of the new rules with smaller chest protectors coming out they changed the arms on them. I had an actual new Koho 590 pro spec, same as the p1 pro spec at the time that came from Jason Labarbara ( same colors as below but with the RBK sized arms) . On the old GSBB I was getting PM's with crazy offers for it because no one had ever seen a pro spec Koho unit. Later on a few years after the craziness of the unit, Roddy at The Goalie Crease worked with Reebok and came out with a retail p1 pro spec unit ( last picture), and that ended the whole unicorn label with unit.
