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.

FusionDri is a highly breathable, extremely waterproof 3 layer fabric with a wicking lining for comfort. Its unique attributes come from the combination of three specialized components. The 15 denier false twisted stretch face fabric is laminated to a very thin (12 - 15 microns) highly breathable membrane and a super light 30 denier bi-component circular knit wicking mesh.
The hydrophilic monolithic membrane is made using a new chemistry resulting in higher porosity in the membrane. To limit the loss of breathability caused by laminating the three components together, they are combined together using a brand new lamination process that reduces the amount of adhesive necessary to bond them into a single fabric.
MemBrain FusionDri uses our exclusive DriClime Mesh bonded to a highly breathable PU membrane. The DriClime Mesh has superior 3 dimensional wicking. It moves moisture from the inside of the fabric via capillary action to the Hydrophilic PU membrane where the moisture is transported through the membrane and away from your skin.
This technology increases the interior comfort of the garment by enabling the wearer to feel less clammy and more comfortable over a wide range of temperatures and conditions. It greatly reduces the condensation and sticky clammy feeling typically of many waterproof garments.
The wicking mesh lining prevents condensation from collecting on the skin no matter what the level of activity due to the 3 dimensional structure of the mesh. The mesh also helps increases the moisture transfer through the membrane by spreading the moisture over a larger surface area maximizing the deficiency of the Hydrophilic membrane to transport moisture through it.
This technology solves the problem of condensation and internal comfort that even the most breathable of fabrics have during high intensity activities.

Breathability: JIGS - 1099 B1: 50,000 gm/24hr
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.
