Safety helmet
Very sturdy, strong and stable. It definitely keeps my husband’s head safe at work. Easy to adjust to fit

Overall good value, fits big heads
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.

Great value!
My experience with this helmet has been just as advertised. I like the compact fit and the fact I can remove the ear protection if I need to. I can wear the helmet in my skid steer and not worry about a big face shield hitting on everything. I got the clear lens. It does have a glare that can make it difficult to see in bright sunny conditions. I think I would have been better off with the tinted lens. The chin strap is okay. If the strap itself was a little wider, it might have been comfortable to wear for longer stretches. Overall I would recommend this product.

Solid quality and functionality
Did some research and looked at many different models. Needed a helmet for commercial and residential use in construction, tree falling and overhead work. Chin strap and built in visor are key. Headphones are good quality for db sound reduction. Integrated unit with all the key elements. Just what I needed. Good value for the money. Would definitely recommend this product for any small business needing to protect employees, even if they don’t like traditional hard hats, this unit is a big step up and removes any excuse about forgetting ear, eye or head protection.

Excellent safety helmets
I am a owner of a Tree Service. I am very satisfied with the safety helmets that I purchased I purchased four of them two months ago installed sena devices in the earmuffs there comfortable to wear it does have venting on the top over 90 degree days they are still pretty warm on your head, but what isn’t so overall I believe they are a good purchase. They do have an eye protection which comes in handy when you’re getting a bunch of wood chips, spitting in your face from the chainsaw They work good for climbing in the bucket and even groundwork all of my guys seem to like them they are highly visible Even when you’re in the air 60 feet overall a good purchase

Excellent hardhat hat, hearing and eye protection solutions.
Once you follow the easy instructions for fit these are are excellent hardhat hats. We used them for Sawyer certification and were much better than separate hearing and eye protection solutions.

I use this every time I fire up the chain saw
It takes a some work to get the fit right. But once it is dialed in it works great. I am not sure how comfortable it would be all day work.

Large improvement
I where hard hats rather often working I'm HVAC/plumbing industry and I have always found them to be heavy bulky and overall uncomfortable where as this hard hat ia lighter and the harness is much more comfortable than a traditional hard hat. Haven't had the need for the ear defenders yet and didn't want the extra weight on the helmet yet. I do like having the built in safety shield since most of the time I lose my safety glasses or don't have them with me.
