How to Measure For and Fit a Body Protector

Body protectors are a mandatory piece of equipment for event riders in the cross country phase of a horse trial. They can also be an asset to riders who are learning to jump, or for those who are schooling young or challenging horses.

Body protectors should be fitted over the type of clothing you intend to ride in. Because a body protector is meant to fit closely to your torso, most riders generally wear one over lightweight clothing, such as a ventilated riding shirt or jersey, with heavier garments and outerwear worn on top. However, if you intend to wear your body protector over heavier clothing, be sure to measure for and try it while wearing these garments.

Various manufacturers ask for slightly different measurements on their size charts: chest, waist and length. However, the chest measurement is most important no matter what brand of body protector you wish to try. This is because most body protectors allow the length to be adjusted through tabs at the shoulders, and most can be adjusted at the waist, too.

Follow these basic steps to determine the correct size body protector to try. You’ll need a soft fabric tape measure, a pen, and paper to record your measurements.


1. Run the tape measure around the widest point of your chest. Make sure the tape is snug, but not tight, and level.



The chest measurement is the most important value in determining body protector sizing.


2. Run the tape measure around your natural waist. Make sure the tape is snug, but not tight, and level.



This measurement is only a guideline as most body protectors can be adjusted at the waist.


3. Some manufacturers require a measurement of the length of your spine. Sit in a chair or a saddle and run the tape measure from the base of the back of your neck to the base of your spine. Take the reading at a point about two to four inches above the seat to avoid interference of the back of the vest with the saddle during riding.




4. Other manufacturers ask for a measurement that runs from the front of your natural waist, over your shoulder, to the back of your waist.


5. Compare your measurements with the manufacturer’s size chart for the body protector you would like to try. Choose the size that most closely matches your measurements. If your measurements fall between a size range provided by a manufacturer, choose the size smaller; body protectors should fit snugly against your torso.

The effectiveness of the body protector depends on achieving a correct fit, as described in the sidebars of this article. You can also order custom body protectors that are made according to your measurements.

Note: Inflatable jackets and vests are designed to be worn on top of a body protector.


Tips for Checking the Fit of Your Body Protector:

Different body protectors will fit you differently depending on the style and manufacturer. Achieving the best fit for you is most important. You may have to experiment with different brands or styles to find the most suitable body protector for you to use. If you cannot achieve an appropriate fit, consider ordering a custom body protector made to your measurements. Be sure to consult a knowledgeable trainer if you have any concerns about fit.

1. Before putting on the body protector, loosen all closures and flex the body protector. With it on, fasten the chest and waist closures to achieve a snug fit. Make sure you have room left within the fasteners for further tightening or loosening. If your body protector is at the end of the range of its ability to be tightened or loosened, consider trying another size or type of vest.

Note: Some body protectors will warm up and begin to conform to your body as you wear them. If this is the case with your body protector, be sure to readjust the closures ten to twenty minutes after putting it on.

2. With the body protector fit securely around your chest and waist, check the front length. The body protector should reach to your breastbone and cover your bottom rib. The shoulders and neckline of the body protector should lie flat against your body; if this fit cannot be achieved —if the vest pulls away from your body— then you may need to try a shorter length. Some styles allow you to adjust the length of the protector through tabs at the shoulders.

3. Check the back length by sitting in a saddle and simulating all of your riding positions. You should have approximately two to four inches between the saddle and the base of the body protector in the back. If the body protector comes in contact with the saddle, it could push upwards near your neck or interfere with your riding.

Hot Weather Riding Tips

The sunny days of summer bring extended daylight hours and the clear weather that means more opportunities to ride outdoors. But some summer days are so hot and humid that they rightly cause us concern over the potential for heat-related health consequences— in our horses and in ourselves.

How much heat is too much to ride your horse? What can you do to keep your temperature regulated while working in the barn or riding? Here are some suggestions for preparing you and your horse to deal with high summer temperatures.

For The Rider
Wear light-colored apparel when you're working around the barn or riding outside. Light colors reflect sunlight. Dark colors absorb sunlight, so when you wear them, you'll feel hotter. Another benefit of wearing light-colored clothing, particularly if you ride on trails, is that you can more easily spot ticks crawling on your clothes before they have an opportunity to attach to your skin.

Our bodies perspire as part of a cooling process. To keep yourself feeling cooler and drier, look for summer riding apparel in a variety of technical fabrics that allow your skin to breathe. Look for fabrics that offer temperature or moisture management by wicking perspiration away from your skin. Coolmax is such a fabric, and it is found in many articles of clothing from many manufacturers, including Tailored Sportsman, Equine Couture, TuffRider and more. Similar fabrics are Airmax, which is found in the Riding Sport line, Cooltex in the Kerrits clothing line and Dri-Lex in the Ovation clothing line.

On the bottom, many riders favor riding tights for summer riding. They're made of very lightweight and stretchy technical fabrics, and are available in both knee patch and full seat styles.

Even socks and gloves are available with wicking benefits. Lightweight gloves from several manufacturers are specifically designed for summer riding. Traditional crochet back gloves are still an affordable, perennial summer favorite too!

Most styles of helmets have built-in ventilation features to help keep you comfortable. Samshield helmets have a discreet ventilation system that allows air to enter the front of the helmet and exit the back; other brands provide ventilation holes and air panels.

Helpful Tip for Showing:
Many show jackets and show shirts are made of advanced technical fabrics that are designed to keep competitors cool and comfortable while riding. Look to jackets from Animo, Grand Prix and GPA that are made of breathable, lightweight fabrics with wicking properties to move moisture away from the body. Look for shirts containing CoolMax, such as those from Tailored Sportsman, Essex Classics and Beacon Hill. Breeches come in a variety of fabrics with wicking properties, too. Finish your show ensemble with summer weight gloves and socks that contain CoolMax. For more information on proper show attire, refer to Correct Attire for the Hunter Ring, Correct Attire for the Jumper Ring or Correct Attire for the Dressage Ring.

Drink plenty of water- your body needs it to function properly. You lose moisture constantly through exhaling as well as perspiring, so you should sip water continually throughout the day. Many people aim to drink eight, eight ounce glasses of water per day to combat dehydration. Don't wait until you feel your mouth becoming dry to begin to drink, and watch for other signs of dehydration such as headache, hunger and fatigue. Beverages containing caffeine and lots of sugar will not help you remain hydrated.

Tip: If you become uncomfortably overheated, put a towel soaked with cold water on the back of your neck, or run cold water on the inside skin on your wrists.

For Your Horse
Calculate and consider the heat index on any summer day that you plan your ride. The heat index will give you a good guideline to establish for working your horse.


Humidity represents the percentage of moisture saturating the air. You can find out the humidity percentage (and often the heat index itself) from your local weather reports. Many reports include this information as a matter of course once a heat wave settles in.

Example calculations:

70 degrees Fahrenheit + 35% humidity = 105 (Pleasant sporting conditions)
95 degrees Fahrenheit + 85% humidity = 180 (Dangerous conditions for physical exertion)

Horses seem to prefer to work at mild conditions, such as 65 degrees Fahrenheit with a low humidity of perhaps 40%. (Just think of a horse's playfulness on a crisp spring or dry autumn day.) So it is up to us to make sure we don't overtax our horses on very hot days.

In combination with the heat index, consider your horse's fitness level and condition. If your horse is fit and trim, has no serious respiratory or medical concerns and has been working regularly as your summer season set in, then he will be fairly well equipped to be worked appropriately on a hot day. Include lots of walk breaks during your ride with time for your horse's breathing to return to a normal rate.

Conversely, if you horse only works sporadically, or if he is old, overweight, coming back from an injury, has a serious medical condition or has just transferred into your area from a cooler region, then you might skip riding on the hottest of summer days. Even a trail ride could cause a compromised horse to become overheated.

Note: If you have questions about your horse's ability to work in warm weather, or the extent to which he should work, be sure to discuss your concerns with your horse's veterinarian.
