Unassisted
From Openwaterpedia
adjective - Unassisted means that an open water swimmer attempts or completes a swim in an open body of water without aid of a shark cage, jellyfish cage, fins, snorkel, paddles, wetsuit or other protective swimwear or gear in order to minimize or eliminate one or more obstacles (e.g., shark attack, jellyfish stings, cold water, distance). In an unassisted swim, a swimmer wears only traditional swimwear without neoprene (as defined by the English Channel swimming community), goggles, and if desired, ear plugs, and one swim cap. In either an Assisted or Unassisted swim, a swimmer can swim together with a Pace swimmer.
