I had just bought a new tree last year and wanted something to protect it while in my storage shed.  This worked out perfectly.  My tree is 7 1/2 feet and very full at the bottom.  It is also pre-lighted.  This worked out great.  It is a tight fit, but I can put all three pieces of my tree in it.  It has a separate place for the tree stand.  It also has straps with buckles to secure your tree.  When I opened it this year, the tree was in perfect condition. This duffel has rollers on one end making it easy to move.  It protected my tree and lights from moisture and dust and dirt, and insects. 

Pros: Good protection for your tree from moisture, dust and insects.
Cons: None
