This is a Pilz 15 Half Inner tent. I used it as an inner tent for a Tentipi 9. There is no hydrolysis, but there is some grass caught in it. Please refrain from purchasing if you are concerned about this. In my opinion, it's in good condition. The instruction manual was sewn onto the storage bag, but I accidentally pulled it and it tore. It's the storage bag, not the main body, so there's no problem at all. The instruction manual is just coming off, and there are no holes in the storage bag.
