Marmot MemBrain® fabrics use a proprietary PU (polyurethane) film laminate that balances the best performance in waterproof, breathable fabric with excellent durability. MemBrain® reduces internal condensation while increasing comfort by reducing the chilling effect caused by condensation build-up. When used with insulated garments or sleeping bags, MemBrain® protects insulation from harsh weather conditions.
Marmot Membrain™ lamination utilizes advance technology that balances the best in performance of breathability, waterproofness, and water repellency with excellent durability. With a minimum of 10, 000mm / 10,000mm performance it's guaranteed to keep you dry and comfortable in the worst of weather.
Marmot Membrain™ technology offers excellent weather protection with interior comfort. The hydrophilic nature of the PU lamination reduces internal condensation and increases comfort range by reducing the chilling effect caused by converting condensation build up back into vapor.
This 2 Layer Lamination combined with superior face fabrics, create a soft, quiet waterproof and breathability fabric with superior performance. With excellent breathability, and long term durable waterproofness this advance fabric technology brings a new level of performance to value conscious consumers.

MemBrain Strata is Marmot's own lightweight waterproof/breathable technology: a lamination technology that rates a whopping 20,000mm in waterproof performance and 20,000 gr in breathability.
Requiring neither lining nor 3-layer construction, strata™ MemBrane® products are by far the lightest, most breathable garments in their categories.
Marmot's proprietary 2.5 layer MemBrain Strata uses micro non-organic particles on the inside of the lamination to increase durability and provide a dry touch instead of that clammy feeling you get from some other products.
The back print pattern is carefully designed to achieve the maximum durability and breathability. Abrasion tests rate 4-5 times better than regular laminates, which is why 2-layer laminates require a separate lining.
MemBrain Strata creates a soft, quiet and compressible fabric while its abrasion resistant design achieves maximum durability.
Compared to other 2.5 layer coatings in the market, our lamination is almost 100% more breathable. In addition, our laminated fabric stretches more than coated fabrics.
