In reply to jim keeley:
Got one.
Slept out fully zipped up in temp down to 0 degrees C , bag was drenched. I have since slept out (down to 5 degrees C )with the door open and the mesh up this has reduced the condensation considerably. This seems equivalent to sleeping with your head outside of a normal bivi bag to reduce condensation.
Its well built with a good groundsheet, front pole held in with velcro which I do not like, otherwise its ok.
Comfy for one (can even cook in it) but snug for two.
The jury is still out as to condensation though. Anybody else had an experience with one?
