Immersion suit fabrics

Ursuit® immersion suits are made of breathable and waterproof fabrics. These fabrics are designed to keep the water out and still allow air and water vapour to pass through. The user will stay dry and comfortable, because body sweat and moisture will vaporize out through the fabric. The function of the fabric is based on the microporous membrane, which prevents the larger water molecules to pass through in, while letting the smaller vapour molecules to escape.

The waterproofness of all Ursuit® immersion suits and fabrics are on a very high level, but you can find the difference in lightness, breathability and durability. Values of these terms are rated below. Typically a lighter fabric means better breathability. The high breathability value means that the user will feel more comfortable because sweat will not remain trapped inside of the garment. For professional and heavy use we recommend to choose heavier and more durable fabrics.

To ensure complete waterproofness of Ursuit® immersion suits, all seams are taped and the zippers and seals are waterproof.

Diving suit fabrics

Ursuit® diving suits are manufactured of several different waterproof fabrics. The breathable and waterproof 4-tex Dive and Kevlar fabrics are similar to the fabrics used in immersion suits. Softdura, Cordura® and HL trilaminate are three-layer fabrics, with a waterproof butyl rubber membrane laminated in the middle of the outer layers. Pursuit diving suit is manufactured of a thermoplastic polyurethane coated polyamide knit.

As with immersion suits, the diving suit fabrics are also rated in terms of lightness, breathability and durability. Depending on the end use and user preferences, the most suitable fabric can be chosen for a diving suit.
