Zippers here allow a tight fit when closed.
The Challenger was best at resisting compression. At a simulated 90 feet, it retained 24 percent of its thickness, compared to the next best at 19 percent and the worst at 10 percent. As a bonus, the outer torso is coated with a slick surface so it dries quickly, which means less evaporative cooling between dives. Pro - All the features. Con - Men's sizes only, though the company reports that women purchase the suit.
