If you are looking for helmets that will let you spar as hard as possible you might want to check these out. They seem to protect quite a bit better that a motorcycle helmet, and way more than a hockey helmet. I took some really hard elbows wearing one, with straights, crosses and hammer fists. You probably don't want to really generate all the power you can when you hit somebody wearing protective headgear while training ( you are still rotating their head on their neck ), but you won't need to "pull" your blows either. These are also used by police for baton training, so they also ought to provide more than enough protection for waster light sparring and drills. They also give you good peripheral vision.
We ordered two of them and should have them by the end of next week, and I will give a more thorough review of them after we weapons spar with them. We paid when we ordered, and when you "pre-pay" you get a pretty good discount. We got two helmets with shipping for $215.
