It'll depend where and when you plan to use the stuff?
Summer day for a bit of wind or shower protection I use a lightweight sailing jacket from Decathalon - Jacket - Clothing - Boating - On sale on Decathlon.co.uk
with either shorts or a set of dry trousers from Palm. Their stuff is pretty good and seems to last ok.
In the winter I use a dry suit from Polar Bears and in between I have a set of Musto Kit bought from their outlet village for not a lot of cash- Bicester Village - Musto Clothing | Jackets - Bicester Village, London
Trago do the Fladen suits at around £100 and they are very warm with good waterproof qualities and I know people thata re quite happy with them.
