Derby Originals Classic Horse Polar Fleece Keyhole Quarter Sheet – Breathable, Moisture-Wicking, Reflective Exercise Rug with Contoured Fit, Tail Cord & Reflective Safety Strips

Our Derby Originals Classic Horse Polar Fleece Keyhole Quarter Sheet or Exercise Rug was designed to provide a comfortable, lightweight winter riding option for riders who wish to keep their horses comfortable under saddle and help warm up and loosen up the muscles and prevent stiffness. These rugs can be worn around the saddle skirt, or over the rider's legs to help prevent chills and keep both you and your horse comfortable at the same time.

• Breathable, Moisture-Wicking Fleece – Made from high-quality polar fleece that wicks away sweat to keep your horse dry and comfortable during cool-weather workouts or post-ride cooldowns.

• Ideal for Cold Weather Riding – Helps retain warmth, reduce muscle stiffness, and prevent chills—perfect for use before, during, or after riding in the fall and winter months.

• Great for Clipped or Show Horses – Keeps clipped, performance, or competition horses warm and their muscles supple while being worked or exercised outdoors.

• Contoured, Dual-Use Design – Keyhole cutout allows for use under the saddle or over the rider’s legs for warmth and flexibility. Tail cord and contoured shape ensure a secure, stylish fit.

• Reflective Safety & Size Options – Includes reflective strips for visibility in low-light conditions. Available in Average and Large Horse sizes in elegant Hunter Green and Navy Blue.

Dried mud, hair, hay, and other debris should be regularly brushed off your blanket. A stiff dandy brush often works best for this. Keeping your blanket clean helps extend its lifespan, as well as help to keep your horse clean and happy. You can also use a damp, soapy rag to remove mud/debris and then wipe your blanket dry. Fleece blankets should only be hand washed and never machine washed. All removable parts should be removed before washing, all velcro straps velcroed together, and your blanket should only be washed in a detergent made for use with horse blankets, or gentle animal-safe cleaners. When washing, use cool water and hand wash gently. Do not use fabric softener with any of our blankets as it will damage their waterproofing and breathing abilities and prevent the blanket from wicking water and sweat off your horse. All of our blankets should be air-dried or line-dried, never put in a dryer. If your blanket becomes nicked or torn, the blanket should immediately be sewn or patched to prevent further damage from occurring.

Sizing Information

These quarter sheets are available in two sizes: Average Horse and Large Horse. We recommend our Average Horse size for most 14-16hh equines, and our Large Horse size for larger horses and Warmblood types between 15-17hh. Our large size is also great for average sized horses with long backs, or for riders who would like a larger keyhole through which to fit their saddle or to fit over their legs.
