Ruggles 5 Blue worksheets are common in Japan, cheap and widely used especially for rain protection. Bright blue stands out, but duller colors in brown and green that blend in naturally are much more desirable for some uses. This worksheet is definitely a heavier quality and I expect it to be more durable, although I have not used it long enough yet to rate specific features, this is not rocket science. I expect it to be well-worth the reasonable price.
