Sailcloth
A Sailcloth is an item used by Link in Skyward Sword. It is little more than a simple piece of cloth meant to slow Link's descent when he approaches the world below from the height of the skies.
When dismounting a Loftbird from a considerable height, Link can use a Sailcloth like a parachute to avoid damaging himself and safely touchdown at his destination. It bears a bird-like emblem similar to the Royal Crest.
