I purchased this item, and after considering I might use it, I only kept it indoors for a few days to get used to it. It has been stored at home since then. Please consider purchasing if you understand this. The front opens with a bellows design, and the top and left side are also mesh. It's a backpack type, so it's easy to move around.
