We use English Bridle leather hides for our leather straps and slings. Depending on the design, the hide will range in thickness from 7 to 10 ounces. Thick and durable, this leather is comfortable to sit on, will tarnish and age wonderfully, and bears more character than thinner hides used for upholstery. Expect it to come with scars and natural blemishes and to wear in to have a beautiful patina over time.
