So today it's perfectly OK to use Gore-Tex in marine environments. Companies such as Kokatat use the same Gore-Tex you find in an REI store to make their paddling gear, such as the Kokatat Wave Drytop, a paddling/water-sport jacket that sells for $339 (www.kokatat.com). But Gore also makes what it calls "Ocean Technology" Gore-Tex, which uses a sturdier lamination formula and heavier face fabrics. It's not designed for hiking around in, but for a wearer who's constantly being doused with cold seawater. It's also expensiveGill's Ocean Jacket goes for $725 (www.gillmarine.com).
So there you go. No worries about using Gore-Tex around salt waterit works well and features in many seaworthy jacket designs.
