We often get questions about whether a customer should purchase a carrier made of twill or canvas. Usually their concern is which will wear better or be sturdier. Twill and canvas are just different weaves; the key to determining how “sturdy” a fabric will be is more its weight. A canvas that is 8 oz. will wear about the same as a twill that is 8 oz. so you should probably just choose based on your style preferences. Most twill or canvas used to make mei tais or SSCs will be at the very least 8 oz and up to probably 12-14 oz. (lighter for mei tais, heavier for SSCs).
