eVent®
Fabric and technology used by multiple companies: oleophobic protective solution is applied at a microscopic level to the PTFE fibers and nodes, allowing the membrane to maintain its natural microporous and air permeable structure. eVent fabrics complete line of waterproof products (ranging from 10,000-30,000 mm) feature the company’s Direct Venting technology, a proprietary air permeable waterproof system that delivers outstanding breathability combined with windproof protection.
MemBrain®
Marmot's proprietary waterproof breathable fabric with a PU membrane features excellent performance at reasonable prices.
Polartec® NeoShell®
Fabric used by multiple companies: very supple and slightly stretchy fabric with a reported waterproof rating of ~10,000 mm and ground-breaking breathability. Unique membrane allows two-way air exchange to facilitate water vapor evacuation. Cold weather endurance athletes who require exceptional breathability are stoked about this fabric.
Polartec® Power Shield® Pro
A highly breathable soft shell fabric that’s waterproof enough to wear most of the time in dryer mountain climates.
Dry.Q™ Elite
Mountain Hardwear’s proprietary W/B fabric . By eliminating the thin continuous PU layer over the PTFE membrane, this technology allows the user to vent water vapor as soon as the garment goes on, without a buildup of moisture and heat.
DryVent® (Formerly Hyvent®)
Waterproof/breathable fabric from The North Face available in several different models. TNF™ gives waterproof ratings in PSI (Pounds per Square Inch); DryVent® 3L, for instance, is rated at 25 PSI minimum after 20 washings with a breathability rating of 750-800 g/m2/24 hrs avg (MVTR) Upright Cup. (Keep in mind that Upright Cup numbers for a given fabric are typically much lower than those from other testing methods).
H2No®
Patagonia’s proprietary W/B fabric, offered in 3L, 2L, and 2.5L versions. Patagonia also offers a full line of GORE-TEX® garments.
PreCip™
A coated technology exclusive to Marmot that offers great value in lightweight rainwear.
Pertex®
Shield+ / AP
Pertex Shield+ is the ultimate lightweight, waterproof fabric for fast moving outdoor activities. It uses a hydrophilic PU membrane to provide a high level of dynamic breathability – the harder you work the greater the breathability of the fabric.
Pertex Shield AP features an advanced air-porous membrane to offer the highest levels of durability and performance for professional and extreme applications. Pertex Shield AP contains a high concentration of uniformly spaced microporous holes that have highly hydrophobic properties. This membrane plays a dual role, giving the fabric both its waterproofness and a high degree of moisture permeability.
