Not well. The couple who owned this tent never even bothered moving in. To be honest I was amazed they attempted pitching it. They ended up sleeping in a summerhouse at the campsite.
In fairness I do own a Quercha base seconds and it has been ok in fairly windy conditions but last week's wind was just too much for this one.
Out of all the tents on the field I would say the Vangos and a Kampa stood up the best. 40mph winds with gusts in excess of 40mph. Non stop torrential rain.
