100% Polyamide Pertex® Quantum – What good is down insulation inside a jacket if the exterior fabric isn't doing anything in support? Pertex Quantum is like the insulation's maid of honor—it's there to make sure all the pieces fall into place. This tightly woven exterior fabric, constructed from fine yarns, has a light, soft feel that allows the insulation to fully loft. It traps still air to improve the warmth and efficiency of the insulating layer, and it's coated with a DWR to dispel wind, rain, and snow.

PrimaLoft® Silver Active | 60g – PrimaLoft® Silver Insulation utilizes a proprietary water repellent finish to keep you warm when wet. A comfortable loft and feel provides warmth, while super-lightweight properties allow freedom of movement for whatever your day may deliver. Excellent packability frees up space for other gear. All these features combine to keep you in the sweet spot of comfort all day long.

High Performance DWR (Durable Water Repellent) – We dare you to go stand in a shower or the next rainstorm with your favorite Flylow jacket on. See how the water molecules roll off the shell fabric? That's due to Flylow's high-performance DWR, a polymer coating added to fabric that makes it hydrophobic, meaning moisture beads up and rolls off, like marbles on glass.
