Thank you for viewing. Please leave a comment if you have any questions. If you want to level up your swimming, the dhb Aeron Wetsuit 2.0 is perfect. Currently, it has been improved to match 2020 with a mix of new fabrics, including the world-renowned Yamamoto Chemical. Strategically placed 2mm neoprene on the shoulders, arms, cuffs, and hem allows for great flexibility in the water and during speedy transitions. A similar thickness also ensures a new-looking collar that fits snugly around the neck without restricting movement. 3mm Yamamoto Chemical 39 Cell panels are used on the front of the torso, and an additional 5mm neoprene adds buoyancy to the front of the thighs. The sleeves and underarms are coated with Hydrodynamic Silicone (HDS) to reduce drag. Completed with an improved, easy-to-reach zipper pull and a zipper from the industry-leading YKK Group, the inside has been softened to avoid unnecessary chafing when tucked inside. Yamamoto Chemical 39 Cell Yamamoto Chemical's rubber material has a closed-cell honeycomb structure, making it extremely lightweight, flexible, and highly insulating. 39 Cell offers an excellent blend of buoyancy, flexibility, and strength, commonly used in surfing, triathlons, and swimming.
