Overton's Pro Wetsuits are now made of 100% ComfoStretch throughout the entire suit, not just in the shoulders and side panels. This new ComfoStretch material stretches in four directions for an extremely comfortable and flexible fit. The better fit means you stay warmer longer. 3mm body and 2mm arms and legs provide excellent thermal protection, but the extra softness makes it feel like a thinner suit with better flexibility. Smoothskin chest panel sheds water and wind for more protection, while flatlock seams deliver added comfort.
