Bright red and super strong material with see through window.  Even has a pocket for you to put a card identifying the contents.  Well thought through in manufacture and material.  Suggest longer interior visibly added a third to compact the branches when attempting to close the duffel.  Easy to maneuver on the built in wheels.  Love, love, love it!!!  Will be happy to see it return every year bringing Christmas alive knowing that the tree was well contained for the period.  Thank you again Wayfair!  Love shopping with you.
