For Arc’teryx, climbing is in our DNA, and Fall 2019 will see the release of our most durable, insulated climbing jacket to date, the Proton LT Hoody.
A true showcase of fabric design talent, it is the best in class for those who are looking for a versatile, breathable, synthetic midlayer for high output activities, while not compromising on long term durability.
• 60x more durable in tests than the industry standard
• High air permeability with thermal protection
• Lightweight synthetic insulation.
WHAT MAKES THE PROTON LT HOODY SO DURABLE?
Years of development have resulted in the creation of Fortius™ Air 20, the story behind it is a testament to an unwavering design philosophy to provide nothing less than the best. In the design team’s eyes, the industry standard fabric was not good enough. To them, there was no other option than to take the hard road by pioneering a brandnew fabric and making it better.
“We designed the Proton LT for our core user who will put it to extremes from climbing to snowsports, so our biggest challenge was creating a textile that was light and open enough to be air permeable, but tough enough for multiple end use. Advanced material technology allowed us to create Fortius 20 face fabric. It has outstanding hardwearing durability as well as high air permeability. The result is my go-to jacket whether I’m going climbing, skiing, or backpacking, I’m stoked to have it!” Brylee Geddis, Designer, Arc’teryx Ascent.
The Arc’teryx Materials Research and Development team worked in tandem with designers and fabric producers to push beyond the industry standards of breathability without compromising on durability. After many iterations and countless wear tests to fi nely tune the balance of performance and durability, the designers ended up with a fabric that is proven to be over 60x more durable in abrasion tests than the industry standard.
