Choose a Y Strap System if you prefer your apron to hug your body more. The Y System utilizes a snug waist belt that holds the apron more firmly around you. Another benefit is that the majority of the apron's weight is supported by your hips thereby reducing shoulder strain. The Y System is fully adjustable and include our signature shoulder epaullets for long wearing comfort. Just remember that ideally the center of the Y should rest high between your shoulder blades to prevent the straps from slipping down your shoulder as you hammer but not so high it pinches your neck. Crafted of 3/4 inch leather strap same as the X Strap System.
