What is Poly Fill?
It is very much like the poly fill that you get inside a pillow or comforter. It comes in long flat lengths rolled up.
The poly fill lining traps heat in the air pockets in the poly filll and keeps insulated. A 300g polyfill means for every square metre of laid out poly fill it with 300g. Much like roof or wall insualation.
Rugging Info:
The performance between say a good 200g and 300g is not as dramatic as alot would think. Choosing which fill you would like comes down to personal choice, your individual horse, how long their coat is or how short you wish to keep it. Another factor to consider is how early or late in the season, in terms of weather and the shelter the horse has access to, such as stable, trees, paddock shelter etc.
Some horses are hotter than others, whilst others feel the cold more, such as young and older horses, or those in not good health.
Heavier fills tend to experience less compression overall and provide the best insulation performance for longer, for those needing that security of warmth.
BUT.......It is important not to over rug your horses also, with multiple un-needed layers for long lengths of time.
