Horse rugs are waterproofed with a porous membrane. It acts like a sponge absorbing rain from the outside and perspiration from the horse from the inside. The heat of the horse will then push the moisture to the outside of the rug where it then evaporates. The membrane can reach saturation point in a large downpour at which point it will leak through to the inside of the rug.
- Is my rug really leaking: The waterproof membrane can reach saturation point in a large downpour at which point it will leak through to the inside of the rug. Also even in cold weather, and very common on a bright but cold Autumn Day, your horse will still perspire but the difference in the temperature on the outside and inside of the rug will cause a condensation build up if the moisture can’t pass through the membrane.
- Check the waterproofing: To test if a horse rug is waterproof, place it over a tub with the outer facing up and pour water into an indent in the rug (away from fittings), and check if the water is held without seeping through.
- Keep air circulating around the horse: Using a rug with even a lightweight filling such as 50g will help keep air circulating around the horse and allow the membrane to work more efficiently at allowing moisture to escape and evaporate.
- Washing guidelines: Follow the manufacturer's cleaning instructions, avoiding hot water, conventional detergents and fabric softeners, as these can damage the rug’s water repellency, breathability, and wicking capabilities.
- Keep the lining clean and don’t worry too much about the outside: A hose down and light scrub of the outside (avoid using a pressure washer or tough brush) is often sufficient but pay close attention to the lining which sits against your horse’s coat and skin. Bacteria can build up from sweat and grime and cause dermatological conditions.
- Storage & drying: Store rugs dry, at room temperature, and avoid direct sunlight or storing them while damp, as this can damage the membrane. Avoid drying rugs for long periods in a sunny spot as the UV light can damage the membrane.
