Lanificio Rogna Review. I received samples of their 350g open weave fabric. Looks and handles great but wrinkles, which according to my feel, much more than other high twists. They have a heavier around of 450g but it has a significant twill pattern I don't like. Hence, I prefer Dugdale Tropicalair, alas UK fabrics are significantly more expensive than Rogna, hence on this they are great.
