Perfect in comfort and for wrapping yourself in a thick, soft, fluffy towel after bathing." We specialize in hotel towels, institutional towels & SPA towels. Bath towels are either 100% cotton or a cotton/polyester blend, usually 85% cotton, 15% polyester. Bath towels made of the blend of cotton and polyester are more durable than just plain cotton towels and will last longer than just plain cotton. However, cotton towels have a higher absorbency then the blended towels.
