Hair
Legolas had never seen so much hair on inappropriate body parts in his long Elven life. Four pairs of hairy feet and four beards assaulted him at every meal. It was enough to kill his appetite, even after hours of walking.
On the other hand, the tough curls did keep the Hobbits' feet warm, and beards protected faces from the relentless wind.
But when Gimli changed his tunic for a warmer one, Legolas saw the wiry, russet hair did not stop at the Dwarf's chin. The thick pelt coated Gimli's neck, chest, belly…Elbereth, did it go as far as that?
