This is an old model Arai Tent Zelt. Based on the illustrations in the instructions, I believe it corresponds to the current Zelt 1 (for 1-2 people). Therefore, you may want to prepare separate thin ropes for pitching the Zelt. By the way, the actual weight was 150g. The packed size is about 110mm x 80mm. A Zelt is, in a sense, insurance for mountain trips. I recommend carrying one, even on low mountains.
