0.66 oz MEMBRANE 10 Taffeta Nylon

What is MEMBRANE 10 and what makes it different from other UL fabrics?

MEMBRANE 10 is a 10 denier taffeta weave nylon fabric. The taffeta weave was sought out specifically as testing has proven it to be much softer and more downproof than other weaves, including standard ripstop nylon. By downproof, we mean the ability of the fabric to prevent leakage of natural down or other synthetic insulation fibers when used in an end product over time (e.g. quilt or jacket). Selecting the optimum weave is even more important for ultralight fabrics as it's inherently more difficult to make thinner, lighter fabrics with high-quality downproofing. In addition to optimum weave selection, we employ a specialized finishing process that is unique to MEMBRANE 10. This process takes the taffeta weave and further improves both the hand feel and the downproofness of the finished fabric.

You say MEMBRANE 10 is downproof. Has it been tested in a lab?

YES. Throughout development we've had MEMBRANE 10 fabric tested multiple times through International Down and Feather Laboratory (IDFL), the industry leader in down and feather testing.

Where is MEMBRANE 10 being used?

MEMBRANE 10 was developed specifically for high-end, ultralight outdoor gear but also finds application in a variety of areas including high-end garments.
