Columbia and Lesfez are American, Wolf Claw is German, and Kellogg is Australian (the design department is in Birmingham, England, and most of the factories are in China). These are good outdoor brands. Personally, I prefer wolf claws. Colombia relies on its own technologies, such as Ometec and Ometan, and has done a good job. Lesfez is well-known in China and is favored by young outdoor enthusiasts, but high-end products mainly rely on Goltes, and Kellogg is cheaper, similar to Orsoka and Pathfinder!
