These haynets are made with a thicker nylon rope to ensure the horse is less likely to chew through the net. The tie string is also thicker as to take the weight of the heavier haylage. The smaller holes encourage the horse to take smaller mouthfuls thus eating slower which magnitudes chewing and minimises boredom. Approx weight once filled: 8.5kg (18lbs). Length of net: 42''.
