Making outdoor jackets fully waterproof and windproof using a single layer of fabric has long been a goal in the outdoor clothing industry.
In this article, we’ll explore the latest fabric technologies that allow jackets to achieve both crucial performance properties.
A Waterproof, Breathable Barrier
The key to waterproofness is creating a barrier layer that blocks liquid water droplets from penetrating, while still allowing water vapor from sweat to escape.
The best women’s ski jacket use membrane technologies like Gore-Tex and eVent to achieve this.
The membrane contains over 9 billion microscopic pores per square inch, each 700 times larger than a water droplet but still 700 times smaller than a drop of sweat. This allows sweat vapor to escape while blocking exterior moisture.
Sealing Vulnerable Points
While the membrane blocks water over the whole jacket surface, the seams, zippers, and pockets are vulnerable points.
The best women’s ski jackets tackle this through seam sealing and specially designed waterproof zippers.
Seam tape helps seal the tiny holes left by stitching, while waterproof zippers contain miniature seals within the zipper teeth.
Battling the Wind
Windproofness relies on the outer fabric rather than the membrane. An air-permeable fabric allows wind to whistle through, stealing body heat.
The solution lies in tightly woven face fabrics, which have too little space between yarns for gusts to penetrate. Brands measure this as an air permeability rating, with 0-5 liters/m2/sec being fully windproof.
| Brand | Face Fabric | Air Permeability |
| Arc’teryx | Nylon | < 1 l/m2/sec |
| Patagonia | Recycled Polyester | 1.3 l/m2/sec |
| The North Face | Pertex Shield | 1 l/m2/sec |
Durable Water Repellency
Outer fabric coatings also help. A durable water-repellent (DWR) finish causes water to bead up and roll off the surface.
This “wetting out” can happen when oils from skin or detergents compromise the DWR over time. Reapplying a DWR spray restores water beading, keeping you drier in wet snow or rain.
Breathability Tradeoffs
The most waterproof and windproof jacket may be a sauna inside. Finding the ideal balance between protection and ventilation for the intended activity matters.
Ski jackets need more weather resistance than lightweight hiking shells. Analyze the conditions you’ll use your jacket in, and choose targeted features accordingly.
The outdoor industry has made huge strides in creating single-layer waterproof, windproof, and breathable fabrics.
Whether battling Alpine squalls or pursuing powder turns, understand the tech behind your jacket to choose the model with ideal properties for your adventures.
With membranes, seam sealing, air-impermeable fabrics, and DWR coatings, you can now have it all in one well-designed piece.
