Schlafsäcke! Mein vollständiges "Wissen" (Teil 1)

It should be common knowledge by now that I like to be thorough! This video, or rather the second part which will be released tomorrow evening, contains all my knowledge on one topic: sleeping bags! However, I forgot some information in the video, which is why Ben's long, flowing explanations are especially "important" this time. ;-) If you notice anything that isn't detailed enough for you, just let me know... I'll add more information about it eventually! ;-) And the second part is almost as long again! I don't want to leave anything out.
