I purchased an Exped Downmat 9 for use on longer trips in severe conditions. I wanted something that would ensure high quality sleep over trips of duration more than a week. I only plan on using this when the temperatures at night are expected to be well below 0F and the sleep surfaces may include things like rock and ice. Snow is a surprisingly good sleep surface and doesn’t conduct heat too readily compared to rock and glacier ice.
I have spent about two weeks using the Downmat under initial safe test conditions; nice weather, normal situations where I would usually be using something like a Ridgerest pad. I want to get the kinks out of the system and understand the pros and cons of the pad before I start to rely on it in conditions that could kill me.
Here are my preliminary observations:
1. It is certainly warm. I’m a warm sleeper anyway, and this pad really does not let any of my own body heat escape. During warmer weather (night time temps probably in the 50 to 70 range) I find it uncomfortably warm. This is a good sign for cold weather use, but perhaps not ideal if someone is planning on using it simply for additional comfort against hard ground.
2. I have a version with a pump stuff sack rather than the newer integrated pump version. I understand why they changed the system. The interface between the valves and the pump sack needs to be watched carefully, as it is a major leak point during pumping. If you have not secured the joint well, air will rush out as you pump. I suggest pumping slowly as well.
3. I don’t find it to be the most comfortable pad I’ve ever used. The pad is baffled, and I find the non-flat surface to be somewhat distracting while trying to sleep. I’ve used flat pads like Thermarest and Ridgerest for years and years, so perhaps this is just a case of me needing to get used to something new and different.
I will post longer term information as I continue to use and abuse this sleeping pad.
