FITS THE LARGER 4L BAGS- STOCK NOW IN. We expect anew larger version later in 2019
The Perfect Udder bag shell turns any 3L Perfect Udder product into a rigid bottle for easy handling at the calf. The spout of the bag locks into place to provide rigidity to the nipple or esophageal feeder so your hands can be free to restrain the calf or guide the tube into correct position. The shoulder strap supports the assembly until you are ready to let the colostrum go.
