We have the Darche Awol in a double. Very similar swag, has full length mesh. I use the head pole all the time, and usually can't be bothered putting the other 2 up. Has enough headroom. Slept in it throughout the heat the other week with all 3 poles up, and yes it got warm, but I was tired enough to sleep! We found the mattress not thick enough, so chucked an old self inflating mat under each side which has done the trick. Our first night outdoors was a rainy one, and we had some seepage through a bottom seam- maybe I didn't wet the canvas enough at home when new, haven't been in rain again yet. Canvas, seams and poles all look good quality. We got ours on ebay last april from a 4x4 supplier who was auctioning them off every couple of days.
Hope that helps, Kris.
