Cressi Thor EBS Adjustable Open Heel Fins, Black/Grey, L

The Thor EBS features a new innovative design developed with all the Cressi experience, offering a scuba diving fin easy to maneuver and to use in any condition..

Two lateral holes discharge the negative forces typically associated with this area and at the same time make for enhanced stability. The blades are molded from two different materials for improved reactivity.. Made with the exclusive 3-material injection system patented by Cressi, which provides an excellent combination of strength, power, comfort, and aesthetics.. Fins come equipped with Cress'si Elastic Bungee System (EBS) which makes use of a round bungee cord band that accommodates all foot sizes for a perfect fit.
