How to Fit & Adjust Horse Rug Belly Surcingles for Comfort and Safety
Updated September 2025
A practical guide for Australian horse owners on how to correctly fit and adjust belly surcingles - improving comfort, safety, and rug longevity in all seasons.
When it comes to keeping your horse safe, comfortable, and well-protected in the paddock, belly surcingles are one of the most important features of a horse rug. They ensure the rug stays securely in place, even when your horse is rolling, playing, or scratching. But for surcingles to do their job properly, they must be fitted and adjusted correctly.
What Do Horse Rug Belly Surcingles Do?
Belly surcingles are straps that fasten beneath your horse’s belly to keep the rug secure. Without them, rugs can slip sideways, twist, or even come off completely, especially when horses are active. A well-fitted surcingle ensures:
- Improved comfort by preventing rug movement and rubbing
- Better rug longevity by reducing strain on buckles and fabric
- Safety for your horse by minimising the risk of tripping or entanglement
Think of surcingles as the anchor that keeps your rug stable in all conditions.
Why Do Some Horse Rugs Not Have Surcingles?
Not every horse rug is designed with belly surcingles. Lightweight designs, such as summer flag rugs or hybrid crossover rugs, are often made without them to maximise airflow and reduce heat build-up. In these cases, the focus is on breathability and climate control rather than extra stability. However, for most turnout and winter rugs, surcingles are essential for keeping the rug in place.
How to Fit Belly Surcingles Correctly
Delzani horse rugs are designed with two surcingles that crisscross under the belly for maximum security. Proper fitting is crucial — too tight, and you risk rubbing and restricted movement; too loose, and your horse may catch a hoof or damage the rug while rolling. Follow these simple steps:
- Crisscross the straps - Attach the front left strap to the rear right buckle, and the front right strap to the rear left buckle. This creates a cross that stabilises the rug.
- Adjust the slack - Leave enough room to fit a vertical fist (around 10 cm) between the horse’s belly and the straps. This ensures freedom of movement without compromising security.
- Check regularly - Surcingle fit can change as rugs stretch with use. Regular adjustments help maintain comfort and safety.
Taking the time to fit belly surcingles correctly not only protects your rug investment but also ensures your horse stays comfortable, secure, and happy in the paddock.
