These calf covers are made from 70% wool and 30% Polyester.
The wool retains body heat and protects from cold winds or rain while the Polyester gives strength to the cover. These covers breath to allow escape of water vapour.
Calves wearing Woolovers grow faster require less feed and stay healthier.
Well worth the cost. Woolover "Ultra" covers feature an extra outer waterproof shell of Emphatex to keep your calves warm and dry even in the most extreme conditions. The Emphatex also extends the cover life considerably and is resistant to dirt manure and bedding.
Regular Woolover covers will last about 4 calves at 3-4 weeks each. Ultra covers should last 4-5 seasons of use.
Use medium for calves 45-55kg and large for calves over 55k. Can also be successfully be used on adult goats and sheep.
