MemBrain® Strata

What is it?

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, MemBrain Strata products are by far the lightest, most breathable garments in their categories.

How does it work?

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.

What are the benefits of this technology?

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.
