A wetsuit protects your body from excessive cold temperature when you are diving. As you go deeper, water absorbs heat from your body up to 25 times faster than air. Adequate protection from cold is necessary to prevent hypothermia, which usually happens when your body is exposed to water temperature below 32° Celsius (90° F). Wetsuits come in many different varieties and here are some features you need to consider.

Cut, length & style
Versatility and warmth are affected by style as well. Irrespective to any extra feature, you have three popular options available:

• Shorty wetsuit: it has short-sleeve and knee-length cover. Your torso is perfectly covered.
• Two-piece wetsuit: it is the most popular option of the three due to double insulation forms. You can also use each piece separately when needed.
