It is not waterproof. You can ser the light from seam holes. Seams are not sealed or taped. Innertent floor is not waterproof either. Not taped. I m very sorry for waiting for so long.
The seller is very kind and nice. THE TENT is for outter tent avarage. Inner tent really sucks cuz no seam seal totally waste if you are not able to fix it.
Idea is perfect, but there are some disadvantages: it is not easy to set up, there are 13 pegs needed to set it up well, and the quality could be better. Anyway, very smart, light and small in the bag. Recommend
