I bought a helmet from airsoftpeak (when is was airsoft park). I think it was an emerson, this one I think is the same, Just different website now
http://www.airsoftpeak.com/fast-ballist ... 10181.html I like it allot. Except it does get hot. Now i wish i would have gotten the one with the vents in it. But i have a large head and this actually has room to tighten it down.
The only problem i have is with the chin strap, It's too short, the chin part actually sits at my cheek. But it's tight enough with my headsets that it doesn't move at all.
I also bought the cheapo rail kit for the headsets to attach to the rails. I suggest going real on those, as mine are crap. They don't lock into place, and assembling them one arm actually broke because the plastic is brittle and wouldn't flex as far as it needed to assemble the parts.
