Size notice:
Feedback from our customers tells, that wetsuits feel small in size. But a tight fit is essential for the suit to work properly. However, beginners sometimes prefer easy usage and larger suits over the recommended tight fit. These customers normally choose one size bigger than the size guide recommends.
