Not having or wearing a covering for the head.

Hoodless → It is formed from "hood" (from Old English *hōd*, meaning a covering for the head) and "-less" (meaning without). The word "hoodless" means without a hood or covering for the head.
Think of being 'without' ('-less') a 'covering for the head' ('hood') — that's what hoodless means.
