How should a wetsuit fit?

A wetsuit should fit like a second skin, with no sagging at the back and no excessive bunching at the arms or legs. It should fit snugly so that only a thin layer of water remains between your body and your suit. If your suit is loose, large amounts of water will wash away and make your suit less effective at keeping you warm. The wetsuit should also fit snugly around your neck (many people wear a bodysuit under their wetsuit to prevent neck rashes). Most women wear a swimming costume underneath for extra protection and support.

Fit is a very important consideration when buying a wetsuit. If your wetsuit doesn't fit properly, it won't keep you warm or provide the flexibility you need to exercise. Consulting a specific brand's wetsuit size chart is the best way to start your search for the right wetsuit.

There should be no extra room in the torso, hips, shoulders, or knees when wearing a wetsuit. A well-fitting wetsuit can be difficult to put on when dry. (Pro tip: wearing socks will make it easier to slip your feet in!)

Once you have started, raise your arms above your head and extend your shoulders. This move should be only slightly restrictive. If you feel a lot of pressure in this movement, then the set is too small.

You should be able to squat and move your arms easily (wetsuits over 5/4 mm are inherently restrictive).
