I have no affiliation with this shop but just wanted to give you all the heads up that Adreno Ocean Outfitters on South Street, O'Connor have a great range of wetsuits including a small selection of Mystic 4/3 steamers.

I was in there yesterday grabbing an Adrenalin 2p thermo fleecy rashie which i highly recommend and they are great value for money.

Sorry Laurie and shops if this post is misconstrued as commercial advertising.
