Question: Nothing is mentioned about sizing. Are we talking xs/52-53, sm/54-55, m/56-57, l/58-59 etc.
Document: looks and feels cool, the price is right, only think if you have a lot of hair or a big head the hard padding inside will be an issue getting it on. Love the drop down visor, a cross between Delta and a chopper helmet, good prop.
it breaks very easily, and the chin-strap on it doesn't adjust very easily. it doesn't even protect your head. I recommend this item to nobody. if you want a better version of this get a $75 one that has an adjuster knob on the back of it so that it can fit your head better. also get a more-expensive one so it can protect your head better. that's all I have to say.
i ordered this helmet by accident but it looked great and felt farlly strong and very use full, but it was very small.&#8203;
This helmet fits well and has integrated eye protection. I put some side shields on it and it works like a champ!
The name implies that it is, but upon further reading into the description, nowhere does it actually claim to be one... my bad, so i can't hold it against the manufacturer.Good product, with little to complain about.
Pros:Great fitting helmet (even for a large noggin)The flip down goggles are a bit tricky to get into position, but function quite well.Very light weightComes with an extra set of padsCons:Extruded polystyrene interior is easily damaged if not handled properly.Interior padding is held on with hook and loop dots.
It needs normal helmet pads because the ones in it are too small and thin. The nvg mount is a little wiggly but I thing it suppose to be like that. The glasses built in are built well and are not wiggly. The only problems are the nvg mount and the pads
Answer: no
