I've never found ultra warm thermals much use for fishing in this country to be honest. They are too hot for moving around and you sweat them damp. Then you have to sit around in damp sweaty thermals or get changed. I've found it better to have light thermals under layers that you can add or remove depending on how hot or cold you are. I just use the cheap Uniqlo stuff.

I use smartwool / icebreaker merino for skiing and you are going through the whole range of temps from sweating due to physical exertion one minute to static and freezing cold / wind (on a chairlift) the next . . . they work brilliantly at pushing the moisture out and are designed to keep you warm; you do need to wear breathable layers over the top for them to work - if the moistures got nowhere to go (by wearing a dirty / muddy top layer) you will get cold . . .

If you have already got some decent gear for skiing then it makes sense to use it. I guess my point was you really do not need to be spending hundreds on Nordic thermals just for fishing in the UK.

Same with expensive Goretex coats and boots. No good when they get dirty, and in the winter my fishing gear does get muddy and dirty.

Breathable layers, no problems

Layers that are of suitable warmth levels, and easy to put on and take off, is definitely the way to go. Sweating your cods off when setting up or spodding, and then sitting down in damp gear is a recipe for a chill. Finding the best combination can however be difficult.
