I don't know but it was possible...Woke up to a wet sleeping bag...I hate camping.
Is there such thing as a blackout tent?

I love camping, don't even mind if it's peeing it down as I've usually got something to keep me entertained, you know the usual, games on phone, music, something to read,
inflatable dolls. ... what I can stand though is setting up or packing up when its raining, that is a pain in the ass!
Yeah the people that made my tent, Eurohike do a blackout one I believe. Not great when its really sunny though as I think you would cook!
Ministry of Sound branded some up for festivals to make a quick buck.
