Don't waste your money on this.
It is fine in dry weather, but not really a 4 man tent, it is a comfortable 2 man.
There is little head room, but it got really damp inside the tent (showers and condensation).
When tightening the ropes, the poles couldn't cope with the pressure and were starting to buckle and twist.
I Bought it in the same deal last year, used it once and then went to a Millets Tent event, where they put them all up outdoors, so you can see what they are really like......I got a quality tent at a great price because there show season was coming to the end.
You would be better putting the money to something a bit better, say Eurohike or Vango (i know there's more)
This one is now a childs play tent....enough said!
Here's the link to Millets Tent events....Its still 2007 showing, but ring your local store (as i did) they should have more info, last years events severly affected by Floods......are you sure you want to camp!!!! LOL
