The only saddle pad endorsed by back surgeons, master saddlers and veterinarians.

About ThinLine Tack

Our mission: Create and deliver a simple, honest connection between rider and horse.

This grassroots company is the result of a chance encounter with an engineer who was developing a thin shock-absorbing material to protect athletes, a specially designed, open-cell foam. Equestrian and entrepreneur Elaine Lockhead Castelao recognized the potential of this foam to enhance performance and reduce discomfort for horses and riders.

Elaine had been competing in Dressage, and while she was riding Lipizzaners she discovered the joy of ThinLine. “I was riding these wonderful baroque horses but was having a horrible time with saddle slippage and keeping my horse comfortable. I came across this foam and Voila! No more saddle slippage, but that was just the beginning of the story.”

As I continued to use the simple sheet of foam I noticed not only how much better my show horse was going, but also how much easier it was to sit the gaits. In addition, I had a retired racehorse in my care, and while the horse was [easily] rattled, I found he was much quieter with the ThinLine. Witnessing first hand how ThinLine impacted these two horses, it became my personal mission to ensure that every horse owner knew about this amazing saddle pad.” It has been a magical adventure making every horse and rider happier and more comfortable.

Who works at ThinLine?

We have a team of five.  As a small entrepreneurial company, everyone wears multiple hats.  Elaine, founded the company in 2004 manages.  Lisa Beam Rose, has been at ThinLine for over a decade and handles most of the Tack Shop Accounts and International shipping.  Berit Brown is the customer service director as well as working with accounts such as SmartPak and Dover.  Eduardo Salabert handles the accounting and the new line of Hitch Pins.  DeeLorean Moore manages all the products in the warehouse.

What are the effects of ThinLine tack?

“The manner in which this product absorbs motion encourages horses to move through the back,” Elaine explains. “We receive stories daily of how ThinLine saddle pads have improved a horse’s movement or a rider’s ability to sit their horse’s gaits. These riders tell us they have little or no back strain and that their horses are working better and happier. It’s a two-way street of comfort, preventing problems, resolving challenges and just having better communication.”

What is ThinLine?

It’s a unique, open-cell technology that distributes shock, weight, and heat laterally along the pad without compressing. The result is 95% shock absorption. But don’t let all the testing and technology get in the way of the ultimate benefit — happier horses and more comfortable riders.

What are some additional features?

The trademark open-cell technology also makes ThinLine horse tack 100% breathable, meaning heat and moisture are not trapped. An anti-microbial agent is also infused into ThinLine girths and horse boots. Also, pressure points created by movement in the saddle and challenges associated with working muscles are nearly eliminated because ThinLine doesn’t compress or slip. It also has more longevity than any other product on the market. Many people get more than a decade out of a basic ThinLine pad.

The ThinLine ride: ThinLine +  vs.  ThinLine.

ThinLine + is a thicker option (1/4″) that offers a higher level of protection. It’s best suited for those who do not ride with a whisper seat — trail riding, stock horse riding and fox hunting, would be good examples. First and foremost, ThinLine + is a necessity for horses with sore backs and those exposed to frequent and sudden impacts. It’s also a great choice for beginner riders and young horses in training.

 ThinLine is a thinner (3/16″) option designed to protect horse and rider backs by eliciting a soft, quiet, elastic connection. If your riding is not in a place where you can focus on nuances a ThinLine pad is a must. Moreover, if you are an effective rider you will greatly appreciate  ThinLine because it reduces the extraneous ‘background noise’ of your movement, which allows your horse to balance and focus better, and makes your seat aides clearer and more effective.

ThinLine can drastically improve the health of a rider’s spine, which is compromised over time. Those who choose  ThinLine are daily riders that are spending many hours in the saddle and need a shock absorber to stay healthy. Horse backs also benefit greatly from quieter riders.

 ThinLine is typically sewn onto our saddle pads, but it is also sold on its own as a basic pad (just the foam). ThinLine Plus + (available in black only) may be purchased as a basic pad as well, or you may add ThinLine + full shims to any shimmable pad. This gives you the flexibility to switch back and forth between an Ultra ThinLine or a ThinLine + ride.

Who am I buying from? ThinLine is a small company with great customer service, we are all riders. Many professionals endorse our products but are not paid for their endorsements. We look like we have a huge footprint, but really we are just a small manufacturer. We don’t invest in big ads, instead, we invest our money in our products. We invest in testing and design to create the most amazing horse tack on the market. We stay true to what brought us into this industry, word of mouth, grassroots growth and development of the best products for riders and horses. We stand behind every product we create.
