Naked swimming
From Openwaterpedia
noun - Naked swimming is the act of swimming in open bodies of water without a wetsuit or any non-neoprene swim cap. In the open water swimming community, a naked swim is not skinny-dipping (swimming without clothes); rather it is performed with a porous swimsuit, goggles, and possibly, a swim cap and ear plugs.
The swimmer swam naked across the lake despite the snow on the coastline.
