what is a decent wading jacket that will not cost too much??
This is the jacket I wear all the time Stephen. As long as it keeps you dry, warm and is breathable you don't need anything fancy. I notice though they are only doing xxl in Sand so they must be discontinuing it :(

This might be an alternative, they do it in Olive.
