What does fill mean in horse rugs?

When it comes to horse rugs, fill refers to the material that is used to provide insulation and warmth to the horse. The fill is typically made of synthetic materials such as polyester or nylon, and it is measured in grams per square meter (gsm).

The amount of fill that a horse rug has will determine how warm it is and what temperature range it is suitable for. For example, a lightweight summer rug may have no fill at all, a between rug may have a fill of 50–150gsm while a heavy winter rug may have a fill of 300gsm or more.

It's important to choose a horse rug with the appropriate fill for the climate and conditions that your horse will be in. A rug with too little fill will not provide enough warmth, while a rug with too much fill may cause your horse to overheat.

In addition to the amount of fill, the type of fill is also important to consider. Some horse rugs use a combination of fill and lining materials to provide warmth and comfort, while others use a single layer of fill.

In conclusion, fill is an important factor to consider when choosing a horse rug. The amount and type of fill will determine how warm and comfortable the rug is, and it's important to choose a rug with the appropriate fill for the climate and conditions that your horse will be in.
