The 2019 Definition 5mm steamer offers more stretch, more comfort and more features. The suit is built with the Body Map System, a manufacturing method that uses a 3D cut, special tailoring and material inserts to create a suit that fits the body like a glove. An Ultraspan chest panel and Stretchtec fabric on the body, sides, arms and legs work together to produce a highly flexible and snug fit, providing extra stretch where it’s needed most. Bigger abrasion-resistant shoulder, knee and elbow pads provide maximum protection. While the new seamless single arm and leg stretch panels with double zippered seals make donning and doffing the suit that much easier. This steamer offers thermal protection well-suited to active temperate-water and warm-water divers.
