After working with very large saws in the late 60"s & early 70"s and owning my private wood lot for 55 years, I have never felt the need for chaps. I do wear arm coverings and an approved helmet with a face screen & ear muffs. When felling large timber, my #1 fear is for my arms/fingers & head/eyes, there is always Murphy lurking with the sneaky barber chair waiting to end your day. I never allow a moving chain near my legs & always trying to keep the power head at arms length. I guess I acquired this years ago when operating big gear drive saws, when the chain stopped, the saw backed out at 70 mph, you better have your legs out of the way!
