Did you know that...
does your horse's shoulder blade not only move forward and backward with every step, but also lift, lower, and rotate slightly? That is precisely why sufficient room in the front area of the rug is so important. If a horse rug fits too tightly at the chest and shoulder, additional tension is created there with every movement. A chest expander provides targeted extra space without needing to choose a larger rug overall.

FAQ
When is a chest extender useful for horse rugs?
It is particularly useful when the rug fits well in terms of back length and depth but is too tight in the chest and shoulder area. Stocky or broad-chested horses, in particular, often need more room at the front without needing a larger rug size overall.
How can I tell if a horse rug is too tight at the chest?
Typical signs include tension at the chest closure, chafing, roughened or broken hair on the chest and shoulders, and restricted movement when moving forward. Even if the rug fits correctly otherwise, the chest area may be cut too narrowly.
What is the advantage of a chest extender compared to a larger horse rug?
A larger rug becomes not only wider at the chest but also longer and more generous overall. If the existing rug fits optimally otherwise, the chest extender provides additional space precisely where it is needed.
Can a chest extender reduce chafing on the shoulder?
Yes, if the cause is a rug that is too tight in the front area. The additional width creates less tension on the chest and shoulder. The soft fleece also reduces friction on the coat.
Can a chest extender make an overall undersized rug fit properly?
No. It is designed to extend only the chest area. If the rug is also too short on the back, too tight in depth, or generally poorly cut, a different rug size or fit should be chosen.
Does the chest extender change the required rug size?
No. If your horse's normal rug size fits in principle and only more space is needed in the chest area, you can continue to use it and supplement it with the chest extender.
Does the chest area remain protected in the rain?
Yes. The chest extender is made of robust 1200D ripstop fabric and has a hydrostatic head of 3,000 mm. This means that the additionally created area is also designed for use with compatible SUNRIDE outdoor rugs.

Further product details
Description
- Ideal for broad horses - more space and freedom of movement in the chest area: For sturdily built horses or those with well-developed shoulders, a standard-cut horse rug may fit too tightly at the front. The chest expander specifically adds extra width, reduces tension across the chest and shoulders, and gives your horse more room for a natural range of motion.
- Easy attachment with quick-release fasteners - simple to retrofit: The chest expander can be attached to the horse rug in a few simple steps and removed just as quickly. This allows you to adjust the fit precisely without needing to choose a different rug size.
- 1200D Ripstop - especially durable for outdoor use: The robust polyester fabric is designed for heavy-duty wear. The ripstop structure also helps prevent tears in the fabric from spreading, making it ideal for daily use in paddocks and pastures.
- 3,000 mm water column - reliable protection in rain: The chest expander is also designed for use with an outdoor rug and reliably keeps moisture out. This ensures the additional chest area remains protected and does not become a weak point in the rug during bad weather.
- With fleece lining - comfortable against the chest and coat: The soft fleece lining ensures a comfortable fit in this area close to the body. It reduces friction on the coat and makes the extender particularly comfortable when the rug is worn for many hours.
- Machine washable - practical after wet and dirty days: Mud, dust, and loose hair can be easily washed out in the washing machine. This makes the chest expander easy to care for and quickly ready for its next use.
- Suitable for various SUNRIDE outdoor rugs - one extender for multiple rugs: The chest expander can be used with various compatible SUNRIDE turnout and winter rugs. This makes it particularly practical if your horse wears different rugs depending on the weather but generally requires more space in the chest area.
- Practical storage bag - neatly stored and quickly at hand: The matching bag protects your equipment from dust and dirt when not in use and ensures organized storage in the stable, locker, or trailer. At the same time, you can keep the products compact and conveniently take them with you to training or competitions.
