I've got the original Airflow suit (picked it up in a sale for not a lot) and the gloves (which though not in a sale were quite reasonably priced).
Both excellent bits of kit. They seem well made and are comfortable.
The suit keeps a good draught of air flowing. I haven't got the Goretex liners which does make it a bit limited - you have to be fairly certain it isn't going to rain or be prepared to get soaked!
Not surprisingly it is not warm so, if the temperature does drop, you can cool fairly quickly. Best range is probably between 60/65F and 90F. Below that is a bit chilly, above that is hot whatever you wear.
The goretex liners might allow you to wear it in lower temperatures but I have no experience.
In summary. Good kit. Not suitable for touring unless you know its going to be dry and consistently warm. Goretex liners will help with this but I don't know how much.
