The Loggerhead is built using Grey Duck's thermo-formed construction - a traditional fiberglass EPS form core with the addition of a tough, ABS thermo formed shell. The integrated rail bumper protects your board where it takes the most abuse. If you're someone looking to transition to a touring shape, but still value stability, you'll find this to be a good option. The Loggerhead is stable underfoot, durable, and a great value.
