Offering straight-forward styling, The Scubapro Oneflex Steamer suits are designed with a triathlon cut that allows for lots of range of motion in the shoulder and arm areas. They are also built using the Pure Design Concept which uses fewer seams and panels for maximum flexibility, and their 2-sided polyester lining is ultra-durable yet stretchy and comfortable. The addition of outside stretch fabric on arms and armpits contribute to making the suits much easier to don and doff while increasing comfort and freedom of movement, design elements much appreciated by beginning divers. The diagonal rear YKK zipper design is familiar to most divers and easy to use.
