The most common and often ideal choice for what to wear under a roll neck jumper is a T-shirt, or nothing at all.
According to Oliver Dannerfalk, co-founder of Rubato, a Swedish knitwear label, the roll neck jumper is substantial enough to be worn with just a T-shirt underneath, if anything at all.
Here's a breakdown of considerations:
-
T-Shirt: A thin, breathable T-shirt (like cotton or merino wool) is an excellent base layer for added warmth and moisture-wicking. This is especially useful if your roll neck jumper is made from wool or another material that can sometimes feel itchy against the skin.
-
Nothing: Depending on the material of your roll neck and the weather conditions, you might not need anything underneath. A fine-gauge merino wool roll neck, for example, can be perfectly comfortable worn directly against the skin.
-
Considerations:
- Material of the Roll Neck: Is it itchy? Does it breathe well?
- Weather: Is it cold enough to warrant an extra layer?
- Personal Preference: Some people always prefer a base layer for hygiene and comfort.
