THE NORTH FACE'S MOST ADVANCED BREATHABLE-WATERPROOF TECHNOLOGY.
At the heart of Athlete Tested. Expedition Proven.™ is the philosophy that authentic athlete insights push their design and engineering teams to propel their products forward. FUTURELIGHT™ technology is no different.
For the first time ever, The North Face has 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 them to create their 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.
