"This suit has excellent comfort and range of motion, thanks to a telescoping torso with suspenders and internal waist adjustment cord. ScubaLab testers were most impressed with the custom-like fit for a stock suit. In those rare instances that the 15 men’s and 18 women’s sizes can’t fit a body size, the FLX Extreme can be made to order. Low-profile valves are standard on the suit, but Si-Tech is available as an option." -
