Having a great bag/system is the key to staying organized when getting ready to go to a performance.
Below is the link to the bag that our company uses. It is called Rac N Roll. This will be the 4th season that I will be using mine and I LOVE IT. The price is very reasonable for the YEARS of use that you will get out of it.
The Rac N Roll is a rolling bag that has a rack built into it. Removable bars store inside the bag until you need to use it as a rack. It is VERY easy to put together. Three bars and you are done. It is made out of heavy duty canvas. A strong but light weight framing system is built into the bag to hold its shape and keeping your costumes from being crushed. Wheel are easy rolling for smooth traveling.
It comes in two sizes~ Small & Large. I have the Large....with three dancers I need every inch of it. The small would be fine for one dancer. In the Large I can store everything I need for three girls to go on stage! Load up your stuff, zip it up and go!
