Rucking backpacks are expensive due to their durability and specialised design. They are made from high-quality materials like reinforced nylon and tough stitching to handle heavy loads and frequent use. Ergonomic features, such as padded straps and weight-distribution systems, ensure comfort and minimise strain, requiring advanced engineering. Their versatility for rucking, hiking, and travel also adds value, making a rucking backpack a long-term investment.
