Forestry Suppliers is where I buy mine. There are 'chaps' that just cover the front and sides of the legs, and ones that have legs you step into. I like the chaps, not the pants. Just my preference.
Kevlar chaps
My first 'cut' on mine caused the saw to stop immediately with kevlar fibers wrapped up in the clutch. Good to go after removing the fibers. I ordered a new pair of chaps cause the old ones had the top layer and the kevlar opened up pretty good. The saw didn't go through the second layer of canvas.
I find them great to use just to get through the briars. Also, I use them when splitting as they give good protection when moving logs about.
The second pair of chaps have a knick out of them, as the saw just bounced off my knee. I didn't even think it was still moving, but the cut it made in the chaps was real convincing to a guy (ambulance driver) who earlier that day was kidding me about my 'clown' outfit (referring to my chaps). When he saw what the saw did, he turned white in the face and said " I'm going to buy a pair of those this afternoon". He knew where we were cutting that he would have been in for some first aid work and carrying me a long way off that hill and out of the woods, if it were not for the chaps.
Another thing to carry with you, is first aid 'first response' things. Something to stop blood flow. A logger in Alaska that was cutting trees for me showed me his trick, and that was to carry a female sanitary napkin (Kotex) in his hard hat above the webbing. He said it was perfect if he would get a cut, to stop blood flow when tied on over the wound. If flow isn't stopped quickly, its curtains.
He also used a 'panty liner' on the headband of his hardhat to soak up sweat. Now I tried that, but my wife wasn't impressed and I didn't like the perfume smell. So I don't do that one. /forums/images/graemlins/tongue.gif
