moisture outside (it is physically impossible) when the Observer is fully closed and is still permeable to oxygen and carbon dioxide into the ambient air. This means it is possible to create an almost completely closed waterproof and windproof environment for sleeping within adverse weather conditions. In case of other fabrics, after 15 minutes of pouring rain (128 liters per hour), the CO2 concentration in the air is over 5% and the O2 concentration falls below 15% inside the shelter... Same goes with the snow. What does it mean for the end user? In extreme weather conditions, sleeping in the crappy one-man tent or completely sealed bivy bag without face opening, it is possible to asphyxiate in 15 minutes. If you would be relaxed, then you could feel the lack of oxygen. But when tired? I don't think so. Such things happened in the past unfortunately. The GORE- TEX fabric is safe, even with all the vents closed. Some will ask, why should I even close the vents? Answer is simple: physics. Heated air stays inside and if there is -10°C on the outside, the temperature inside would be around +3°C in the head and core area. Of course, the moisture will appear on the sides but the only downside is some moisture on the outside of the sleeping bag. Instead, we can sleep comfortably even if not a top-notch extreme temperature rated sleeping bag. It's all about the military DNA of the Observer Plus: it was meant to make rest in adverse conditions possible. Not relaxing. The insulation from the outerworld is pretty serious. The bottom is completely waterproof 100% Polyamide 6.6 with all seams taped. No soaking or leaking is possible. Another thing is non- EQUIPMENT
