Love this thing! We like the waterproof nature of the bag as we store our tree in an outdoor storage shed. The bag is very large and can probably hold a disassembled 9ʻ tree, but resist the urge to cram it into one bag as the weight of the tree makes it hard for one person to transport. We stored the top 2 pieces of our 3-piece tree in one bag and the larger, heavier bottom piece along with a metal tree collar and a 3ʻ rug for under the collar in the second bag.
