Private Reserve 3-Layer Fabric

Private Reserve 3L is our benchmark for quality, protection, and comfort. All Private Reserve fabrics have a waterproof rating of at least 20,000mm and a breathability rating of at least 20,000 gm/in2.

1. FACE: 140-Denier Nylon Plain-Weave

By employing a high-density weave, our face fabric that not only feels smoother and softer, but it sheds snow and water better than ever. Despite its supple hand, Private Reserve 3L retains our trademark durability and high-abrasion resistance.


DERMIZAX® EV is a proven and highly versatile 20k/20k-rated waterproof breathable polyurethane laminate manufactured specifically for heavy-duty applications. Its vapor-permeable hydrophilic structure allows water vapor to pass through, and expands as your body temperature rises to increase breathability during heavy exertion. It is 100% windproof, and does not lose its waterproofing performance when stretched repeatedly over time.

3. BACKER: 20-Denier Nylon Tricot Knit

Our internal backer is a smooth, 20-denier nylon tricot that not only lends a new level of comfort to our durable hard shell garments, but offers enhanced breathability and wicking performance.

DWR: Durable Water Repellent Coating

A high-quality DWR coating enhances the performance of the fabric by protecting the surface from dirt and oils. We only use DWR coatings based on the environmentally friendlier short-chain (C6) fluorine compounds, which won’t degrade in the environment into PFOS and PFOA.
