Erwin Ros + 5000m | KilimanjaroGoirle5/512-2-2017High altitude tent was top! It helped me reach the summit of Kilimanjaro. The delivery was fine and the support via e-mail was also excellent. I think the pick up went well too. Sleeping in the altitude tent and training with the module was never boring for me, also thanks to the calm build-up. The effect on the mountain was very noticeable: I hardly had any problems with altitude sickness. However, I had hardly slept and had caught a cold, which affected my saturation. The first night it was 96% and it slowly dropped during the following nights to 84% just before the climb. Again, I had no headaches or nausea, just fatigue. I walked together in the group with another person who had slept in one of your altitude tents and she too did not suffer from altitude sickness. We were the only ones in the group who actually got through the days well. All in all, very satisfied! I would recommend it to anyone who wants to climb.
