Thanks for your input Hoops. I used the Dainese Avro on the bike today and initially it felt great fitted wonderfully and was rather flattering (rather like a corset). The elastication works a treat and the internal airflow is very good - that combined with the fact that the elastic is along the thigh and into the crotch area and under the arms I was completely frozen after 20 miles and returned the suit as it is great if you are in Almeria or in the South of France but in Blighty it could only be used on warm summer days. I am therefore going to start looking afresh for kit that does not have a load of elastic and perforations.
