There is an enormous variety in cotton berets, but not all qualify as a true Basque beret. Firmness, weight, breathability, shape steadiness and general comfort are all equally important in making a true cotton Basque beret.
South Pacific Berets works with only four traditional and artisan Basque beret manufacturers who have also specialized in working with cotton. 

First and foremost: Bonigor from Buenos Aires, offering a large range of cotton berets in diameters varying between 28 and 35cm.
The Fábrica Nacional in Montevideo is, like Bonigor, a major supplier of cotton berets to the gaucho’s, farmers and workers of the South American pampas and fields in a range of sizes, colours and weights.
France’s oldest beret manufacturer Laulhère and young manufacturer Le Béret Français have both taken a more contemporary look at the cotton beret; Laulhère leading in high fashion and Le Béret Français in the development of super-light, easy to wear and eco-friendly berets of recycled cotton and other materials.
