St Patrick's Guild has been selling the exceptionally well-cut albs of Slabbinck for many years. This Belgian company is world renowned and has distinguished themselves as makers of distinctive and beautiful vestments. The very popular Ravenna fabric is made of 70% polyester and 30% cotton to give each alb a pure white color. The Ravenna fabric is made with a more open weave then similar fabrics. This allows the albs to breathe better and keep the wearer cooler than most other albs might.
