Will your cham be in it or are you just storing it when it isn't being used? As long as the mesh doesn't sit soaking wet 24/7 and isn't out in full sun it should last a long time. Some insects can chew through the mesh, squirrels or mice might chew holes in it. The plastic frame could split if it freezes. The zippers tend to wear if they are used every day for a long time I've noticed. I don't know if they might corrode in high outdoor humidity. But, for a temporary outdoor basking cage or a travel cage they work great.
