strength skillcape

A Strength cape can be purchased for 99,000 coins from Sloane (or Yadech Strongarm after While Guthix Sleeps) at the Warriors' Guild by players who have achieved level 99 Strength. It is the Cape of Accomplishment for the Strength skill. Strength capes are green in colour, and have a red trim if the player has more than one level 99 skill. It is very common to see this cape worn as the Strength skill is very popular amongst players who like to deal more damage in melee combat. There are currently over 65,000 with 99 Strength making it the most common by 10,000 players, followed by Cooking, Fletching and Attack.
Even if a Strength Pure has 1 Attack, they are still able to enter the Warriors' Guild to purchase the cape.
