Here is the size chart for selecting Speedo wetsuits for men. These wetsuits consider height, weight, chest, waist, and hip measurements when determining your correct size.
If you happen to fall between two sizes, choose the size where you match most of the measurements. Generally, the most important measurements are the waist and chest. A wetsuit should ideally not fit too loosely; if there are many air pockets or βbagsβ around the suit, it is too big for you.
