Your new Buell wetsuit should feel like a 2nd skin. Like it's part of your body. Obviously a wetsuit should fit tight. The only question is tight, or tiiiiiggght?
Quick answer? If you are between two wetsuit sizes on the size chart below, decide if warmth or ease-of-entry is more important to you.
For warmth go with the smaller size.
To make it easy to get into, go with the larger size.
