Pertex aims to toughen up next year's line of down jackets.

The ingredient brand best known for providing an extremely lightweight exterior for down jackets is beefing up its recipe for the fabric with the debut of what it's calling CS10 technology.

The new tech, to be featured in fall/winter 2016-17 pieces by Berghaus, Montane, Mammut, Peak Performance and Salewa, utilizes yarns with diamond-shaped filaments, which lock together better than traditional circular-filament yarns to provide a very stable construction.

“These tightly interlocking filaments give the fabrics superb abrasion resistance along with improved water-beading properties,” company officials said. “And while highly durable, these fabrics are exceptionally soft to the touch, extremely downproof, and lend a beautiful sheen.”
 
The new tech and fabrics will be on preview at this January's winter trade shows, including Outdoor Retailer Winter Market in Salt Lake City, UT, January 7-10, 2016; and ISPO Munich January 24-27, 2016.
