The Mens Kwark Navy Undersuit is intended for divers swimming in very cold waters, using laminated dry suits.

The material was produced on special order for the U.S. Army Special Forces Divers, in order to meet all the required parameters for long-diving in cold waters.

The Kwark Extreme takes the success of the Tech series by adding a dual-layer on core areas of the body. When a diver is in proper trim in the water (flat with arms in front and knees bent) the air migrates away from the front of the diver on the lower area of the arm, the chest and abdomen, and thigh area. This causes these parts of the body to suffer from quicker cooling than other parts of the body. These areas are protected in this undersuit by a double layer of Kwark’s material ensuring the highest level of protection for the areas prone to less air protection. The double-layer allows more air to be trapped between the layers of the material.

One-Piece Design

This suit is designed to be a one-piece suit to ensure that the body is fully protected at all times under the drysuit. In colder conditions a one-piece design is much better than two-piece.

Pee Valve Slots

The Kwark Extreme comes with two slots both left and right for the urine tube to feed through.

Zipped Pockets

The Kwark Navy Extreme features three zipped pockets as standard. One on the left chest and one on each side of the waist. Perfect during the surface intervals on dives to put keys or wallets in
