Fleece Horse Rugs
Polar fleece horse rugs are a great was to add extra warmth without the weight.
Fleece - is a synthetic fabric made by first creating polyester, spun into yarn and then woven together to create (in this case) different types of fleece fabric. Polar fleece is a popular choice when looking for a travel or stable rug for the cooler months. As a rule, horse fleece rugs aren't as strong or durable as those made of wool, but it is cheaper and will definitely work towards keeping your horse warm.
Tack Tip - Thicker fleece (higher GSM amount) will retain its heat insulation properties better than thinner products which will thin out quickly with regular use. Also, choose anti-pilling fleece for better performance. Ask your online saddlery expert for advice.
