Bought new from the manufacturer and used twice by Joe (he didn't like it).
184g on my scales. In immaculate condition. Easy to get into and out of thanks to the chest zip. Has a loop sewn into the mesh to lift it away from your face while you are sleeping. You can attach this to the handlebars of your bike if there are no trees around. It is the one furthest away in this photo. I was using a small pole I got with a mosquito net in this set-up - the pole is not included, although I am sure Stu could make you one.
These are water resistant, not waterproof so should be used with a tarp.
It's the same as this one:
