This is the model that started it all. All other ALiner models are variations of this orginial design. Classic earned it's name by satisfying customers for over 30 years. It's not the largest or the smallest. It's not the haeviest or the lightest. It's what Classic owners like to call "just right." Versitile, adaptable, and comfortable with everything you want and nothing you don't. The Classic is just that... classic.
