Ideal for portraits or chroma key, the Blue / Gray 5 x 7' Collapsible Backdrop Double Sided Pop Out Twist from Neewer has a blue side that facilitates dropping in the background of your choice via chroma key and a gray side that renders a slightly cooler quality of light with brighter reflective performance.
The background has a loop that allows support by a light stand, while it can also conveniently lean against a wall. The background twists and folds down to approximately 1/3 its open size to fit in the included bag.
