What is ThinLine?

ThinLine is a thin, shock-absorbing non-slip breathable foam.  Endorsed by surgeons, master saddlers, riders, and veterinarians.

Where is the ThinLine?

Sewn onto the panel of all our English cotton saddle pads. This panel creates a pocket that allows shims to be used.

The manner in which this product absorbs motion encourages horses to lift their backs, developing strength and top-line.  It has been endorsed by Veterinarians, for horses, as well as Spinal Surgeons for riders. It is a top pick for Master Saddlers around the world. Equine Chiropractors and Massage Therapists carry it on their trucks to keep horses going strong, supple, and relaxed.  Trainers and riders find it a trusted product to improve rider equitation.

    I really like this Trifecta Cotton Half Pad. Shims are available and becomes very useful if I have to wait between saddle fittings. I can shim my saddle and continue to ride the horse in comfort.

    I love this pad. I’ve had it for three years and use it everyday on multiple horses.
    I like how easy the shims are to adjust. You can get shims for front back and middle. You can layer them if needed.
    I washed well and is also great as a impact absorbing pad with out shims. It helps my one saddle fit a three of my horses. I couldn’t ride without it.

    Love this product! Having the ability to add shims if/when I need them has been really helpful for my OTTB as he has changed shape over the years. I am a big believer in the benefits of thinline products for sensitive backs and I almost never ride without them. I definitely noticed a difference with my horse when I started using thinline pads under my saddle and he is much more comfortable.

    Despite other reviews claiming this pad comes with shims, mine arrived without them. That was the entire reason I bought it. Very disappointed to discover there were not any shims included.

    Why a half pad if saddle fits? I use to use Ami cell but when I bought a new saddle – the saddle fitter said it was too thick. The thin line adds protection for my saddle keeping it from absorbing sweat and adds just the right level of protection for my horse while I can still feel close contact in my seat. 17 inch cwd saddle fits perfect with Medium trifecta Thin Line. Love the Brown Color!

    I wasn’t convinced this pad made much of a difference until I forgot to use it one day. My pony was so unhappy with me! He was hollow, tossed his head, and inconsistent. I haven’t forgotten that pad since, and he’s back to his soft, round, consistent self.

    So far so good! Good fit under my 17:5 dressage saddle. Like the spine protection. Brown works well with my Loxley saddle. Would buy again.

    Are any shims included with the pad?
  1. Q Are any shims included with the pad? answer now

    Hi Lisa, thanks for your question! All of our pads are made with ThinLine shock absorbing foam under your saddle, which gives you and your horse all of the great proven ThinLine benefits. Shims can be purchased seperately if needed to adjust your saddle fit or to add a full extra layer of protection and comfort to your shimmable pad!

  2. Will this fit under an 17.5 saddle?
  3. Q Will this fit under an 17.5 saddle? answer now

    Thanks for your question! We typically recommend the medium Trifecta for 17.5" saddles.

    The seat size doesn't always tell us the size of the saddle and panels. So to be extra certain, you can measure the footprint of your saddle and compare it to the measurements of the Trifecta's shown here in the sizing tab

    19.75″ spine length
    14.5″ across the widest part of the seat

    21.75″ spine length
    16″ across seat

    23.25″ spine length
    16.5″ across seat

  4. Can this half pad be used under a western round skirt saddle?
