ThinLine

Overview

ThinLine Global is a horse tack and saddle pad manufacturer specializing in equestrian comfort products designed to enhance performance for both horses and riders. The company is known for its proprietary open-cell foam technology that distributes shock, weight, and heat laterally without compressing, achieving 95% shock absorption. ThinLine products are positioned as premium comfort solutions that maintain the connection between rider and horse while reducing pressure points and improving breathability through its 100% breathable material design.

History

ThinLine was founded by equestrian and entrepreneur Elaine Lockhead Castelao after she encountered an engineer developing a shock-absorbing foam material originally designed to protect athletes. Recognizing the potential of this foam for equestrian applications while competing in dressage, Castelao began developing ThinLine products to address saddle slippage and horse comfort issues. The company started with basic saddle pads and gradually expanded by partnering with quality manufacturers to create collaborative products. In 2012, manufacturing partners began producing ThinLine products, and in 2018, EquiSew Inc. was established to exclusively manufacture ThinLine products.
