Replace the X Strap with a Y Strap System to transfer the apron's weight onto your hips vs shoulders. The Y System utilizes a snug waist belt that holds the apron more firmly around you. 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 highly durable 3/4 inch water buffalo leather strap same as the X Strap System.
