I think the Green Irish Tweed is suppose to be an Irish Spring knock off and I don't really like that scent, so I haven't tried it..
Ditto what Shunt said....it does not smell anything like Irish Spring. It's a dupe of the popular Green Irish Tweed cologne made by Creed, supposedly a favorite of Sean Connery from what I heard once.
From RE, I really love these. They last long in my soap:
Barbershop 1920's
Tuscan Fields
Redwood
London Fog
