Very nice hard hat. Ear muffs creak when moving but work very well. Fits my very big head. Visor is Z87 impact rated and can be used easily over my prescription glasses. Chin strap is easy to adjust or remove. The only con I can think of is that the vents can be hard to open or close if the ear muffs are installed.

It's a good helmet. An AK in one, safety helmet, eye protection and hearing protection in one. Ear muffs are a little tricky to manipulate but not a problem. I would recommend.

Compared to the cheap forestry helmets they sell at tractor supply and Home Depot this thing is a Cadillac!. It is very comfortable, however after trying out a co-workers Kask helmet it does leave some to be desired... My biggest complaint are the ear muffs are very cheap, they dont have detents to pop out so you can talk to someone and to swing them up and over the helmet you feel like your going to break them. Easy fix, you can replace them with better quality for $30. Other than that it's a decent helmet, even after the $30 ear muff upgrade it's still way cheaper than a $400 Cask helmet. I will be buying another to have for home since I've left my home one at work.

I work on a trail maintenance crew and need to replace my old helmet because it kept falling off my head. My son told me about this helmet. This helmet had all the accoutrements I was looking for. It's a three in one helmet that has hearing and eye protection, plus a comfortable strap to keep the helmet on my head. I recommend this product.

My ears are very sensitive thus I found the click of the chin snap next to my ear painful and resulted in ringing. . Fine I put on ear plugs first now knowing that. Placing the head phones in open and close position is Loud as well. Still that said this is a very nice product and I use it a lot.
