The RAB Firewall Pants are waterproof trousers designed for men who need reliable protection from rain and wind during outdoor activities. Made for everything from hiking in changeable weather to daily wet-weather commutes, these pants help keep you dry without getting in the way of movement.
Built with a three-layer Pertex Shield construction, these pants offer a fully waterproof and windproof barrier that still lets moisture from your body escape. The outer shell is a recycled 100% polyamide fabric treated with a fluorocarbon-free Durable Water Repellent (DWR) finish, so light rain beads off instead of soaking in. With a regular fit, they’re roomy enough to layer underneath but won’t billow in a stiff breeze or catch on branches when you’re on the move.
Pertex Shield is a laminated fabric system where a waterproof membrane is sandwiched between a tough outer layer and a soft inner lining. That means no loose membranes to peel away over time, resulting in long-lasting waterproofing and a quieter, more flexible feel. The DWR treatment is a coating that makes water bead up and roll off the surface, helping prevent the outer fabric from becoming saturated. Polyamide, commonly known as nylon, adds strength, abrasion resistance and quick-drying performance for wear that holds up well on rugged trails.
