| Most BUFF® multifunctional tubulars are manufactured in an environmentally responsible manner at our factory in Igualada, just outside Barcelona, Spain. Millions are sold worldwide each year. |
| They are manufactured through a patented weaving process using a special 100% recycled polyester yarn, in which the thinness of each filament is less than 1 dtex. |
| The pores on the outer surface of the fabric are made very small to prevent water and wind from passing through the fabric, but at the same time ensure that the pores on the inner surface are large enough to make the fabric highly breathable. |
