I use the Labonville wrap around chaps, have used the Husky's from Lowes and Stil wrap arounds. Just wore them out and tried different stuff. I like the wrap arounds, just more protection and they stay in place better for me. The big thing is to wear some sort of chaps, everytime. Hard toed boots can save some pain, I've cut my boots, not my foot-yet. Eye and ear protection, if combined with a helmet even better. If just cutting firewood, not in the woods, I just use ear muffs and glasses. Use glasses under the helmet face guard.
About 50% of chainsaw injuries are above the waist, may consider the protective shirts. I haven't gone there yet.
Make sure your chain catcher is still in place, it really helps stop the loose chain, but they do disappear.
Usually burn 6-10 full cords a year, cut a little bit of timber. So far have not had a reportable injury, 60+ years old. But i have nicked chaps and boots that could have been bad if not for the extra layer. Been working with farm safety stuff for 40+ years, have seen way too much nasty stuff that could have been prevented.
