I have had the following if its any help
Titan waterproof smock - zips fall to bits and the hoods are designed wrong, you get a draught down the neck and the hoods dont cover the face fully.
Greys smock - fri**in freezin in the cold but nice and lightweight, waterproof but the water runs up the sleeves too easily, particularly if you hold your rod.
Daiwa coastal smock - the business, has a fantastic hood that wraps completely around the face and neck, it also has neoprene cuffs to keep out draughts and water. Also made of a very hardwearing material. Just make sure sure try one on for size. I had to get the xxl and im only a 42 chest but with long arms. Its my favourite coat when it gets really cold and you can even fish without a fleece underneath. Its a bit like a puffa jacket.
If its not too cold I would stick with the greys.
