I use an 18" piece of 6" diameter flexible drainage pipe (called a big O around here) and a bungee cord to hold it on as a light weight guard for the chain, and a strap of some kind, like an old guitar strap, duffle bag strap, or even rope to throw over the shoulder. Keep the saw on your back or under your arm, or where ever its comfortable and doesn't flop around. Hope your saw is light.
