How Warm Does A Wetsuit Keep You?

Measured in millimeters, the thicker the wetsuit is, the colder temperatures it allows you to handle. A 7mm suit can withstand temperatures around 38 degrees. Have a suit that is less than 2mm, and you can only go into water around 70 degrees or better.Dec 5, 2017

Will a wetsuit keep you warm in cold weather?

Neoprene is a great heat insulator, so when this is combined with the multi-layer build of the wetsuit and the thin layer of water trapped between it and your skin, the different factors together make a supreme heat insulator against the cold temperatures of the sea.
