Neoprene vs. PE Foam

By using neoprene, a synthetic rubber foam as basic material, all aquata suits possess an indestructible warmth- and buoyancy-mechanism. Even if the suit is damaged and water penetration occurs, the neoprene's enclosed air bubbles can preserve a high degree of body warmth.

Some competitors use PE foam instead of neoprene for insulation. Due to its inside structure PE foam is rather inflexible. Therefore some manufacturers use it for three-layer-suits. Through this low flexibility, suits have to be either very wide, or if they are cut more narrowly, universal application to different body sizes cannot be guaranteed since they are unable to be stretched like neoprene suits.

Three-layer-suits with an insulation-layer made out of fleece are very vulnerable to damage. If the outer hull is broken during the evacuation process, the suit looses all of its insulation due to water ingress. Even smaller amounts of water lead to an immediate cold-bridge, which connects the skin with the wet fleece and therefore leads to a significant loss of body-warmth.

If the PE foam has a minimum thickness of 5.0 mm the insulation results of these suits are acceptable. However there are problems related to storage. PE foam, stored and folded once, does not elastically return to its original shape again. The material compressed in certain areas does not regain its original thickness and does therefore loose large parts of its insulation ability.
