Activities
The Bircham combines premium merino wool with performance-driven, engineered fibres. The outcome: a highly functional sock with a natural feel. Each stratum of the Three-Layer Aquasealz™ Composition assists in the release of internally generated moisture, aiding thermoregulation. The Aquasealz™ hydrophilic membrane is completely waterproof, keeping feet dry in the wettest of conditions. Additionally, the ankle length enhances the overall breathability of the garment.
Mountain biking, trekking, trail running and hiking are all in the scope of the Bircham.
