Players that have at least one other level 99 skill aside from Woodcutting will have a green trim around the edges of the cape. If 99 Woodcutting is the only level 99, the cape and its edges will be the same dark tan color.
When buying the cape, players also get a Woodcutting hood which matches the cape but gives no stat bonuses.
Like all Capes of Accomplishment, the Woodcutting cape has a unique emote. The skillcape emote will still work in Free to Play worlds even if the cape is shown as a "Members Object" as long as you are wearing it. If you are in a members world and are wearing it, you can right click the cape in your "Worn Equipment" tab, and chose the option called "Boost" which will temporarily raise your Woodcutting skill to 100 for a short period of time.
