Flank Strap Basics: What It Is and Why You Need One

If you ride a horse, you’ve probably heard the term "flank strap" tossed around at the tack shop. It’s a simple piece of leather or synthetic material that wraps around the horse’s side, just behind the ribcage. The main job? Keep the saddle from sliding forward during a ride, especially when you’re doing fast work or jumping.

Most riders think a flank strap is optional, but in many disciplines – like western riding, barrel racing, or any high‑speed event – it’s practically mandatory. Without it, the saddle can shift, causing sore spots for the horse and a loss of balance for you.

How to Fit a Flank Strap Correctly

The first step is choosing the right size. Measure the distance from the horse’s withers down to the top of the hip bone. Add a couple of inches and you’ve got the length you need. Many brands sell adjustable straps, so you don’t have to be exact, but a good fit still matters.

Next, place the strap on the left side of the horse, just behind the ribcage. You’ll want it snug enough to keep the saddle in place, but not so tight it chokes the horse’s breathing or restricts movement. A good rule of thumb is that you should be able to slip a hand under the strap with some resistance.

Secure the strap using the buckle or Velcro fastener. Double‑check that the strap sits flat against the horse’s side – any twists can create pressure points. Once it’s in place, mount the horse and test a few walks and canters. If the saddle stays where you left it, you’ve got it right.

Maintenance Tips to Keep Your Flank Strap in Shape

Cleaning is easy. After each ride, wipe the strap with a damp cloth to remove sweat and dirt. If it’s leather, apply a light leather conditioner once a month to keep it supple. Synthetic straps can be rinsed with mild soap and air‑dried.

Inspect the strap before every ride. Look for cracks, frayed stitching, or worn buckles. A damaged strap can fail at the worst moment, so replace it as soon as you see any signs of wear.

Store the strap off the ground, preferably hanging on a rack or laid flat. Avoid folding it sharply, as that can cause creases that weaken the material over time.

Finally, remember that a flank strap isn’t a one‑size‑fits‑all solution. Different horses and disciplines may need slightly different styles – some riders prefer a wider strap for more stability, while others opt for a narrow one for comfort. Experiment a bit and find what works best for you and your horse.

With the right fit and regular care, a flank strap becomes a low‑maintenance piece of gear that can make your rides safer and more enjoyable. Give it a try on your next outing and notice the difference in saddle stability. Happy riding!
