We packed it all into our W3 3,5mm full suit. Even if all Brands out there offer a 3 mm suit does not mean that Waterproof followed the pack. Our fastidious Waterproof customers expect more than just a normal standard suit from us. Our APP pledge requires top notch performance. We started by including all the features you have come to expect in every Waterproof product like gender specific fit and sharp Scandinavian styling. Additionally we included all of the features from our heavier lines like relief zippers in the neck, rash guards in the wrist and ankles and a 3D construction sculpted to fit human movement.
