We took the solid tradition of the Farmer John and added innovative features, making the Ultra John the ultimate 3mm wetsuit. TiCoat™ insulation makes it warmer, MicroPlush™ lining makes it more comfortable, and PowerSpan™ panels give you extra freedom of movement. All the seams are glued and blind-stitched, and the seat and knees are armored with rugged TuffTex™ material. YKK® double- pull relief zipper and ankle zip.
