Fjallraven Karl Pro Hydratic Trousers Men's

These Fjällräven Karl Pro Hydratic Trousers for men are built for outdoor use, offering a versatile bottom layer for hiking, trekking or general trail work. They blend practical design with fabrics that adapt to variable weather, so you can focus on the path ahead.

The trousers are cut in a regular fit from a 65% polyester and 35% cotton blend, giving them durability without sacrificing drying speed. Their G-1000® Silent construction is specially woven to reduce noise when you move, and it holds up to abrasion from rocks or brush. A fluorocarbon-free impregnation adds a water-repellent finish that sheds light moisture while avoiding harmful chemicals, so damp mornings won’t slow you down.

G-1000® is a dense, high-performance fabric originally developed for expedition wear. It’s treated with a wax-based, fluorocarbon-free impregnation that repels wind and drizzle but still lets moisture vapor escape—keeping you comfortable in changing conditions. The “Silent” variant further minimizes the rustle typical of synthetic blends, which is handy if you’re birdwatching or moving quietly in the woods.
