Wet gear is always an issue. I store my wet tent and rainfly in lightweight sil-nylon bags. I'll separate them, if both the tent and rainfly are wet. I also store my sleeping bag and pad in sil- nylon bags. The wet tent goes in my rackpack along with the bag and pad. I've never had a problem with mold , mildew, or getting the other gear in the racksack wet. I have had to carry the wet rainfly for 3-4 days. but I do take things out and dry them as soon as possible.
Blue bar- tent, Yellow bag-sleeping bag, gray bags compressible pillow and sil-nylon ground cloth, orange bag- Thermarest pad. There is usually another sil-nylon bag included to separate the tent and rainfly if the fly is wet.
