Encyclopedia : W : WA : WAT : Waterproof fabric
Waterproof fabrics are usually natural or synthetic fabrics that are laminated to or coated in some sort of permanently waterproofing material, such as rubber, polyvinyl chloride (PVC), polyurethane (PU), silicone elastomer, and wax. Examples include the rubberised fabric used in Mackintosh jackets and inflatable boats.
Waterproof/breathable fabrics
(alternate spellings include 'waterproof breathable' and 'waterproof-breathable')
Waterproof/breathable fabrics are defined as fabrics that will withstand over 1000 millimetres of water (9.8 kPa) pressure without leaking (see hydrostatic head), whilst allowing water vapour to pass through. Their most common use is in outdoor sports clothing and single wall tents, because of their ability to allow sweat to evaporate while remaining impervious to rain.
Some common waterproof/breathable fabrics are:
- Gore-Tex
- eVENT
- Sympatex
- Drilite Extreme, made by [Mountain Equipment]
- HyVent, made by [The North Face]
- H2No, made by [Patagonia, Inc|Patagonia]
- Conduit, made by [Mountain Hardwear]
- Triplepoint Ceramic, made by [Lowe Alpine]
- Precip, made by [Marmot]
- Closely woven cotton
- Wax impregnated cotton or cotton/polyester mixes (such as those used in Barbour coats and Fjällräven's G-1000 fabric)
