Keeping warm when fishing during the colder months of the year is crucial for both comfort and performance. Alongside a good fishing hat, good thermal base layer can make all the difference, providing essential warmth to keep you enthusiastic, put simply if you get cold you won't fish effectively.
Using a layering system with the base layer as the undergarment on top of a mid layer and robust waterproof clothing is the optimal to stay warm and dry when on the bank. I've tried a range of different base layers over the years, and while all these products aim to do the same thing, they each have unique attributes that may suit some people more than others. This guide will help you decide which base layer is best for you.

When choosing a base layer for fishing, there are a few key factors to consider. First, think about the material. If the garments aren’t comfortable, you simply won’t wear them, rendering them useless. Look for materials that are moisture-wicking, breathable, and quick-drying. Popular choices include merino wool, polyester, and synthetic blends.
Second, the fit. A good base layer should fit snugly but not tightly. It should allow for freedom of movement without restricting your range of motion. It is surprising how much you will move when on the bank, even when using a bedchair or sat on a seatbox, and as such, anything that feels restrictive will be magnified.
Finally, layering. A base layer is just one part of a layering system. You may want to add a mid-layer, such as a hoodie, and an outer layer, like a waterproof jacket, depending on the weather conditions.
