A very useable and smart belt. 4cm one preferred to 4.5cm for every day use. Lighter, better knot and less bulky. Compared with Hirota belt which are nice in their own way, I’d say this costs almost double but it definitely much much better imho. I’d opt for this over any other belt if i had to choose only one. Belt wear apparent and starts around 3-4 months of regular use.
