Aquaman Women’s Bionik 2.0
Best for: Upper body flexibility seekers
The highlight of the Bionik is the high-end neoprene—Yamamoto GIGA #40, for you rubber geeks—on the shoulders. This supple neoprene is 1.5mm thick and offers substantial range of motion through the upper body. The suit has a reverse zipper, which is a useful feature as you’re exiting the water because it makes the suit easier to take off, but you may need some assistance zipping it closed. Rubber Dome neoprene panels on the torso provide mild stability but do not overly correct your form, making this suit ideal for experienced swimmers with a more efficient stroke. The collar has a seam-free design that’s intended to minimize irritation, but our tester noted some mild chafing that may vary from swimmer to swimmer.
