MEMBRANE 10® is an ultralight 10 denier breathable, calendered, and DOWNPROOF taffeta nylon. We developedMEMBRANE 10® with the goal of making a UL fabric that offers excellent wind/water resistance, incredibly soft hand feel, and tested downproofing in both lab and field use - all at a great price point. At 10 denier and a finished weight of 0.66 oz/yd2, MEMBRANE 10® is one of the thinnest/lightest taffeta nylon fabrics on the market today.

MEMBRANE 10® is currently available in Jet Black, Charcoal Grey, and Burnt Orange as inner shell fabric option on all Made To Order quilts. Click HERE to see just how MEMBRANE 10® performed in the Rotating Box Test for Downproofness.

Finally got to open my Christmas present of a new 20*F Flight Jacket Top Quilt and Hanger 11 Tarp. I know, it's early but my wife and I won't spend Christmas together this year so we had our own Christmas early. As always, fantastic work! Mike

The 0*F Zeppelin Under Quilt arrived today. Man that thing is beautiful So nice not to have the typical browns and greens. Makes me want to sell some of my other quilts and get them in different colors. Just wanted to say thanks so much for it...Dave
These quilts are exactly what I had pictured in my mind before I even contacted you...they are PERFECT! I have several TQ's from JRB and Hammock gear... while they are nice quilts they simply do not even compare to what you sent me. I am completely blown away by the quality in your products. Thank you again for your wonderful custom quilts...Sam
