I've been using this helmet since it's iteration as a 3000, then went on to have a couple of them as a 4000, and have had three or four 4500s since. When National Sports went out of business in Canada a couple years back, I picked up two more just in case this happened. I still wear one with a bird cage for men's league and another one for coaching. It's also almost time for my son to get a new lid and I keep telling him how great the 4500 is, not sure he agrees, but we'll see what he likes best.
