Understanding how a poly-fill lining works can go a long way to insuring your horses comfort this winter. The lining works much like your roofing insulation - it traps heat in the air pockets in the poly fill lining and slows down the radiant heat out of the rug and away from the horse.

We use 300grams of polyfill in our "Alpine' range of rugs. 300gr is ideal for Australian Winters in all but the far north. . You will see some manufactures produce a 200gr or less version. This is more for marketing, than actual benefit to your horse. Anything less than 250grams of filling simply doesn't have enough body to provide a sufficient insulation effect.

Our research shows, that its not until you get over 250grams+, that you start to get enough body to make a difference. The other downside with a 250gr or less of filling - is that the poly fill does flatten down - and after a few months you will be holding your rug in your hands and be contemplating buying another one. A 300gram rug should last you many seasons.
