TREW builds for the rigors of backcountry freeriding, using materials and construction methods that reflect our commitment to quality, durability, and innovation. We work closely with our factory during all stages of development and production to ensure consistency with our highest standards, with the constant goal of making our garments lighter, better fitting, and more functional without sacrificing durability.  


Private Reserve 3-Layer Fabric

Private Reserve 3L blends rugged durability with lightweight performance and flexible comfort. After two years of development and testing, we are proud to offer this proprietary waterproof breathable fabric in all of our hardshell garments. 

FACE: 140-denier nylon plain-weave with a Durable Water Repellent finish

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.   

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 compared to our previous backing fabric. 




SuperFabric® utilizes ceramic laminate technology to provide an extremely durable and flexible barrier against abrasion and cuts. Its interlinked geometric structure prevents hard objects and sharp edges from reaching the fabric below, making SuperFabric® the ideal material for protecting the inner legs and cuffs of all of our pants and bibs.
