Review: Mountain Equipment Aerostat Down 7.0 Mat Regular
This is a down insulated air sleeping mat for colder times.
The pack is not too massive for a winter sleeping pad, and it comes with a good looking repair kit. (Own work. License: CC-BY-SA.)
With an R-value of 5, this sleeping pad is good well below freezing temps. Tested at around -7C, though not directly on snow. Slept well, so the essentials are in check.
The mat opened but not filled. The stuff sack doubles as a “wind sock” pump. (Own work. License: CC-BY-SA.)
My only complaints are with the stuff sack. It’s possible to roll the mat and get in that way, but in practice this is really hard with your fingers numb. I would recommend just stuffing the mat into the sack.
As is visible above, the sack also works as a pump. It’s nice that you don’t have to buy it separately, but it’s also not as good as a traditionally shaped pump sack. Gets the mat filled though.
All in all this is a decent winter sleeping mat.
