Well, the BBC weather forcast did not disappoint - minus 4 at 8pm as my daughter and I settled down for the night.
The Marne tent, was easy to pitch using 3 poles and the fly and inner pitched together in about 5 minutes. I was really impressed with the tent. The two windows and the front let in good light, there was excellent ventilation throughout, and no condensation in the morning. The tent is described as a 'Technical Cotton' (polycotton) but is much softer to the touch than the main stream polycottons available on the market.
The front porch has it's own ground sheet and the rear storage does not, but allows for other 'dirty' equipment to be stowed away. Both the doors from the inner tent have the fly net integrated and the rain porch to the front is a great little addition.
We used the Human-Comfort self inflating air mats with optional foam topper and cover as well as Human Comfort sleeping bags (both to be reviewed soon). I have to admit it was really toastie. The childrens bag is really thick - a technical cotton outer prevents dampness and a cotton inner enables the body to breathe.
