Tim ten Klooster + 8000m | Mount EverestZwolle5/527-10-2023I used your altitude tent again in July/August, for the reason of climbing Manaslu in Nepal (attempt 2) last September. It resulted in the successful ascent of the summit on 21/9/23! I did not suffer from headaches or lungs or otherwise for a moment. I did have hallicinations from 7600 and descending to about 7000 m. I was also very tired, but that is allowed at this altitude I guess 🙂 I thought you guys would like to know, what the result was.
