Back when I used to climb trees for a living I always wore my hard hat with ears and face shield, or climbing helmet in the tree, safety glasses, chainsaw chaps when on terra firma, chainsaw boots and gloves on the jobsite. Then I'd think nothing of cutting firewood on my own time in my shorts, hiking boots, tank top and sunglasses. Till the wife came out one day during my homestead firewood operation asking why didn't I wear the same protection cutting trees at home that I did at work? DUH! Needless to say the SOPs at home changed. Sometimes we take things for granted in our "leisure" time.
I've had enough close calls over the years with widow makers or small limbs dropping from the heavens not wear a dome cover in the woods. A small, dead 1" limb seems harmless enough until it falls 80' and lands end down. Can you say javelin?
