Wetsuits are design for a tight yet not constrictive fit. Wetsuits will expand approximately 10% when they get wet. You should have a full range of motion with any wetsuit even when dry. Neck, Wrist, and Leg Seals should be tight enough to keep water from flushing through the wetsuit. The following manufacturers size charts are intended as a guideline to assist you with selecting the appropriate fit. Most manufacturers size charts run a little tight. If you have any doubts about these sizes, or are not looking for a tight fit, our recommendation is that you move up one size level. Weight is the biggest factor in sizing. It maters most on shorty suits and height becomes a factor on long suits. If your shorter than the recommended height level by a little its ok. Body Glove makes some unique sizes like the Medium/Large (M/L) and the Large/Tall (L/T) on their upper end products, some starting with the Crush line above, to fit you just right. They also make custom suits starting at $119 in a shorty.
