These tree tubes are great. Use the black plastic and keep weed growth away from the trees for the first few years. Cut the plastic away from inside the tube to let any condensation run down and water the tree. 60" & 72" really help protect the trees from the deer.

I use the biggest diameter I can get, usually the 4 3/4" size. The optimal free netting for the top keeps birds from nesting inside.
