We have found we never seem to get what we want, they are never quite big enough except for the holes which are normally too big. We have now designed a net that is halfway between a hay and haylage net. The standard hole size for a haynet is usually 4.5 to 5 inches, so we have made a net with 1.5" to 2" holes, which allows the horse to eat normally without gorging itself. This is a serious haynet, length 5 ft, diameter 38". It is made of webbing that is much thicker than normal and is built with a metal ring at the bottom and sliding metal rings at the top.
