The 2019 Definition 3mm wetsuit offers a level of warmth and comfort any warm-water diver will love. It is built with SCUBAPRO’s Body Map System, a manufacturing method that uses a 3D cut, special tailoring and material inserts to create a suit that fits like a glove, provides extra stretch where it's needed most, and offers excellent warmth, comfort and durability. Proven N2S (Nylon 2 Sides) construction offers the perfect level of warmth and comfort for warm-water diving. The infrared fleece interior lining reflects body heat to ratchet up warmth even more, plus it's comfortable as can be against the skin. It’s the perfect thermal protection for any diver.
