The Kwark NAVY undersuit is a high performing undersuit, nearly all of the Atlantic Scuba instructors and staff now use them. They keep us warm, even in cold quarries in the middle of winter. A few of us use the thinner Kwark Power Stretch Pro suits during the summer.

Most people who try them, buy them. Here are some of the comments made by customers:

  • The most comfortable suit I have ever worn
  • It doesn’t restrict me at all
  • It is so easy to get on and take off
  • It was so warm when I put it on, I couldn’t wait to get into the water to cool down
  • It’s brilliant, I don’t want to take it off after a dive

The main selling point of Kwark under suits, is the fact they are so flexible. They hug your body and move with it, rather than gaping and the trapped air shifting around. This is what Kwark say about their suits………..


Polartec® Power Stretch® Pro™ fabrics feature body hugging 4-way stretch and are very breathable. They keep you dry when you sweat and provide warmth without weight.

These fabrics feature a proprietary construction with two unique surfaces: a durable nylon outer layer is wind and abrasion resistant; the soft polyester inner layer pulls moisture away from your skin keeping you dry, warm and comfortable. The fabrics excel at handling the demands of the next-to-skin environment.

Available only in black with red stitching in the U.K.

The NAVY Body Warmer is intended for divers swimming in very cold waters, using laminated dry suits.

The material was produced on special order from the U.S. Army Special Forces Divers, in order to meet all the required parameters for long-diving in cold waters. Thermally, the NAVY Body Warmer is equivalent to traditional warmers based on Thinsulate weighing about 400 g/m. However, the NAVY has many advantages, about which users of such conventional warmers can only dream of.

  • The primary advantage of the NAVY is its flexibility. This is not a medieval knight armour with which thick warmers are associated with.
  • It is very comfortable and gives you a full range of motion.
  • It’s easy to put on a dry suit on it, NAVY doesn’t roll up
  • Provides very good air flow.
  • It is very light, weighing less than 1.5 kg.
  • Compared to conventional warmers, allows reduce the ballast of at least 2 kg.
  • Maintains great thermal comfort, also after drenching.
  • Perfectly wicks sweat away from the body.
  • It is very well impregnated anti-bacterially and does not smell.
  • Dries up in a few hours (after complete flooding or washing).
  • There is no limit to number of washing, it can be spin-dried.
  • Tailor-made durable flat seams provide comfort.
  • It is soft and pleasant to the touch. It does scrub or irritate the skin.
  • Three pockets, including one with a zip
  • A stand-up collar doesn’t collide with an isolation near the neck
  • A fold protects from cooling down through the zip, “a garage for the zip” protects the neck and a flexible sleeve
  • A two-way zip (zipping with double sliders)
  • Strings allow the air to flow freely into the dry gloves
  • Comfortable constrictive rubber bands in legs
  • Slots for a P-valve and a heating cable – at the request with a possibility to agree on its location
