Merino wool is undoubtedly the best in the world. It’s known to regulate body temperature, so it will lock in heat when you’re cold but allow it to escape when you start to get hot.
The naturally fine wool makes this jumper beautifully soft and lightweight. It debsises the warmth of a much thicker knit, meaning you can wear it alone with smart trousers and feel comfortable on cold days.
This jumper will also act as a neutral backdrop for a patterned suit or one in a contrasting colour.
