Thermofill Heavy

Designed primarily for cold-water drysuit diving requiring maximum insulation, and suitable for extended surface use in severe cold.

Size

S M L XL XXL

The Thermofill Light undersuit is made from a technical multi-layer material that makes the suit breathable, flexible, and water-repellent. The outer layer is X-Tex® membrane fabric, the insulating layer is Thermofill fiber, and the inner layer is comfortable fleece.

The structure of Thermofill insulation is unique. The material does not lose its insulation capacity even after many times of washing. The Thermofill insulation doesn't break up like most cotton-wool insulating materials, and therefore it doesn't get lumpy or flattened with use or after washing. The material also keeps most of its insulation capacity even when completely wet. The insulation of the fabric used in the Thermofill suit has been measured using the international Clo value. The Heavy model has a Clo value of 1.97, and the Light model has a Clo value of 0.83.

The suit has vent holes in the armpits and on the left arm to assure free circulation of air inside and outside of the underwear, and to allow air control of the dry suit at any ascent speed. The suit has a zipper with double locks, a chest pocket with zipper, as well as large thigh pockets. Elastic fabric in the collar, sleeves and ankles, and a wide waist band. Thumb loops and leg retainers ease dressing.
