Four years ago, we introduced MEMBRANE 10 nylon taffeta as our lightest, softest, and most downproof fabric ever.

Since then, we've searched the globe for a 10 denier ripstop to match. A fabric that could offer the same performance and buttery soft hand feel with maximum durability.

And finally... we got it. Today we're proud to introduce MEMBRANE 10 ripstop nylon.

At 0.75 oz, M10 RS sits in between typical 10D and 15D finished fabric weights, and with good reason...

Instead of a "barely there" ripstop or compromising on downproofness, M10 RS uses a significantly thicker ripstop grid and super high thread count, tight weave construction.

The result is a more durable ultralight fabric and exceptional downproofing (see IDFL results HERE). With a CFM (i.e. air permeability) of 4.4, it's also highly wind resistant for its weight. This makes it an excellent choice for a UL shell on an underquilt.

Lastly, as part of our larger green fabric initiative in 2019, M10 RS uses an ECO friendly, C6 PFC free DWR (Durable Water Repellant). This gives the fabric water resistance without the negative environmental effects of fluorocarbon based DWR formulations.

Maybe the best part for you is that we're launching with a full $2 OFF per yard through this week ONLY. The launch price is already reflected on the website. Regular price of $10.95 /yd will resume next week.
