HKM Style Anti-Fly Rug
Updated: May 2026 · Written by the Rincón del Valle technical team
HKM style fly rugs play a key role in a horse's well-being. They protect from cold, rain, insects, or help with drying after exercise.
What to consider when choosing an HKM style fly rug?
Below we review the technical criteria that have the most impact on the final decision. These are the same ones we apply in the store when a customer asks us a question.
- Weight. No filling (0g) for summer and drying, 100-200g for mid-season, 300-400g for winter. Clipped horses need more weight.
- Waterproofing. For outdoor use, measured in millimeters of water column: 1,500 mm minimum, 3,000 mm ideal for rainy areas like Galicia.
- Size. Measured from the center of the chest to the base of the tail. This measurement in cm is the rug size (95 to 175 cm for standard horses).
- Closure system. Double cross surcingles for greater stability; tail flap optional but recommended for outdoor use.
