Step In Jacket

The Step In Jacket is a popular style with cold water divers for many reasons including it’s warmth and versatility. The jacket covers the arms, torso and thighs and can be worn on its own in warmer conditions, keeping the upper body warm while offering good freedom of movement for the legs. It is commonly worn over a Farmer John and/or with a Hood with Cold Water Bib to add additional layers of insulation for colder conditions.

The Jacket has Raglan sleeves with pre-bent elbows, and zippers can be in straight, diagonal or side zipper configurations.

Our dive suits are made with 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. All seams are glued & blind stitched for durability and have Lycra bindings for flexibility. They are available in various thicknesses with your choice of interior Nylon lining or Neoskin, and have non-corrosive Vislon zippers with interior flaps underneath to prevent water from entering.

This jacket is custom-fit to your measurements for maximum warmth and comfort. Stock sizes in 7mm neoprene are also available. All JMJ wetsuits are made to last and keep you warm for many dives to come.
