I don't recall ever seeing chaps at Home Crapo or Lowes. You're wise to invest in a pair but I'd buy good ones from a site sponsor and use the GC for something else (ie bar oil??).
Don't buy Stihl chaps either. The straps are not sewn securely to the caps. Walk thru some brush and they snap and pull right off.
I have seen a Husqvarna "Kit" at Lowes that had hard hat face shield and chaps all included. Since I allready had mine I dind't look too close at it.
