Here is the size chart for selecting Orca wetsuits for men. These wetsuits are based on your chest, height, and weight when determining your correct size.
If you happen to fall in between two sizes, choose the size that matches most of the measurements; generally, the most important measurements are weight and chest size.
Ideally, a wetsuit should not fit too loosely. If there are many air pockets or βbagsβ around the suit, it's too big for you.
