Tarptent Contrail up for grabs. For anyone not familiar with them, they're a hybrid design which means single skin with an attached bathtub groundsheet and netting joining the 2. There's also a full net inner door so the thing's midge proof even if you keep the front doors open. LOTS of venting options so condensation issues are taken care of. Very quick to set up and weighs 750g (plus pole + pegs). Poles supplied but you'll need to find some pegs.
Same as the pics but the pics aren't the actual tent. £120 to your door.
