I have not shipped one shirt yet, but I would think someone would put the shirt in something also. I can't see the cardboard holding up in rain.Rodney said:I just shipped some shirts to Australia and I used a weather resistent type polybag container. But the tyvek envelopes are also pretty weather resistant.
Inside of the shipping container, the shirts were folded and bagged (the bag was sealed).
I don't think most people use cardboard style boxes without some sort of inner protection.
