Farmer John

Cold-water divers have used the classic Farmer John wetsuit for decades; a one piece sleeveless suit that covers the legs and torso. While shown here separately, the John is typically worn under a long sleeve Beavertail Jacket or Step In Jacket to cover the arms and add an additional layer of neoprene around the torso for maximum warmth.

The John is made with pre-bent knees for ease of movement. All seams are glued & blindstitched for durability and have Lycra bindings for flexibility. Like our other dive suits, the Farmer John is usually made from durable dive-grade neoprene that has better “memory” than other types of neoprene, meaning it will resume its thickness even after being compressed many times at dive depths. Various thicknesses are available and Supratex knee pads come standard on our Farmer John.

This wetsuit is custom-fit to your measurements for maximum warmth and comfort. All JMJ wetsuits are made to last and keep you warm for many dives to come.

Measuring Instructions

  1. Take your measurements using a cloth measuring tape and write them down. Have someone measure you if possible, otherwise you can measure yourself.

    Chest: the largest circumference around your chest - usually around nipple line. Measuree should lift arms out to side, place tape around chest, then lower arms to side. Make sure tape stays level around the back.

    Waist: the smallest circumference between your chest and buttocks; not where you would measure the waist for a pair of pants, but normally a couple of inches higher, just below the base of the rib cage. If your waist is larger than chest or buttocks, take largest circumference of waist area.

    Hips: The widest circumference of your lower hips. Be sure to keep the measuring tape level.

  2. Find your size on the chart starting with the Chest, then find the best size matching your Height, Waist and Hips
