FUTURELIGHT™
OUR MOST ADVANCED BREATHABLE-WATERPROOF TECHNOLOGY.
- At the heart of Athlete Tested. Expedition Proven.™ is the philosophy that authentic athlete insights push our design and engineering teams to propel our products forward. Our FUTURELIGHT™ technology is no different.
- For the first time ever, we’ve added air permeability to a waterproof membrane. The nano structure of the FUTURELIGHT™ membrane allows air to pass through for better venting and breathability without sacrificing waterproofness and durability.
- This new nano-fiber structure enabled us to create our most lightweight, breathable membrane to date. An ultra-thin, nimble garment that feels comfortable and provides the protection needed against the elements in the harshest environments.
