Test trials prove effectiveness
Research trials supervised by North Dakota State University revealed significant performance gains for calves wearing the original Woolover. Dairy calves gained an extra 14 pounds during the 65-day trial versus non-blanketed control calves.¹ Beef calves, wearing a blanket of different composition, gained 37.8 pounds more than their controls.¹ Unseasonably mild temperatures made the gains even more notable. Research further showed that the Woolover is most beneficial during the first three weeks for dairy calves kept outside or in hutches, and for the first 60 days for beef calves in dry lots.

High-performance outer shell

• The Woolover Ultra gives you Emphatex™, a waterproof outer shell, with the original Woolover underneath, for proven warmth and protection. Together, they repel wet, cold and windy weather more effectively, so calves stay drier
• Emphatex also adds four times greater strength to the Woolover Ultra, helping keep its shape calf after calf
• When a calf's body temperature rises, the membranes in Emphatex expand. Like wool, this outer shell breathes, allowing excess heat vapors to escape while further reducing interior condensation
• Calves wearing the Woolover Ultra retain their natural body heat and expend less energy trying to stay warm. Instead, they convert energy to growth
