Excellent values of elongation and recovery. This means it fit and acts like a second skin providing you with unrestricted range of motion you have not experienced before. To quote surfers, “it just feels better.” Durability- Yamamoto’s proprietary closed-cell manufacturing process also results in a neoprene that is also highly durable while remaining extremely stretchy that feels and acts like a second skin. It doesn’t get loose over time like traditional neoprene that in a new suit, “feels” great, but quickly loses its elongation recovery as the cell structure breaks down. Traditional neoprene acts more like a kitchen sponge (in terms of water absorption) in many cases increasing the weight of a wetsuit by 2x or more requiring more body heat to warm the water, more energy to paddle and maneuver in a restrictive heavy water laden suit, and much longer drying times between surf sessions.
