We like any wetsuit that keeps us in the water so we can surf longer, but the Kassia 3/2 Of Earth Wetsuit is especially splendid due to its environmentally conscious construction. Premium Limestone Neoprene uses natural limestone, neoprene chips, and sustainable energy to deliver the same comfortable protection we expect from any wetsuit. Even the glue used to seal the suit up is solvent-free. We also appreciate the bit of wind protection at the chest and back.
