1/ Why chaps, he's not running a saw?
2/ Why a vest when there's fluro moisture control shirts
3/ With all gloves your hands sweat in that heat, that's a tough one to fix.
4/ Why a helmet, if there's nothing over head, however mandatory on building sites even when there's nothing there! Could have a face shield without the helmet and switch muffs to plugs.

Could be argued he should have a chem suit on, even disposable overalls with respirator etc.
They say dont leave pets and kids in cars when the heat is on. Temperature rises rapidly. I wonder if any tests have been made what the temperature rises to in that little place between your scalp and the helmet. It's hot here most of the time, this years summer was the coolest I can remember ever. But I know before I even get near a tree with all the gear on sweat is pissing out of you, then comes other problems like dehydration, headaches and cramp. It's an art working in the heat and knocks people around big time.
