I bought 2 Tree Duffel Rolling Storage Bags, My Husband and I just put our 9 foot Front Gate Christmas Tree which is very large around into the 2 Duffel Rolling Bags, we bought 2 because we thought that it wouldn't fit into one bag with the 6 foot & 3 foot swags and we were right!! I would think one Duffel bag would work if your tree was 9 foot skinner tree. These bags are tuff. Zippers seem to be tuff though plastic and the rollers are GREAT! The interior part that has the pulls to secure the tree will surely help with bulb breakage, It may be more expensive but they are worth it!
