QUALITY DETAILS
• Heavy-weight webbing core
• Four layers of fabric
• Triple-stitched stress points with box stitching
• Heavy nylon bonded thread on all straps
Leashes:
All leashes begin as 6 feet of nylon, ending up around 5.5 feet once the handle and hardware are added. We do not offer alternate lengths, but we can make it adjustable if you’d like—free of charge.
Some colored plastic hardware is only available in 3/4” and 1”. When needed, we use metal triglides in place of plastic.

CARE
Machine wash, air dry. No ironing needed.
