We have MICH-style helmets back in stock, finally. These are non-ballistic, suitable for training, milsim, or airsoft, but very realistic. They have adjustable straps and removable padding. These were hard to get for a while, but luckily we found a new source. We also carry the MultiCam helmet covers that fit over this puppy, so you can match your loadout.
And good thing is they are priced affordably.
