Choose cotton knitwear if you want something breathable and easy to look after, and wool if you want proper warmth. Neither is better. It depends on the weather, your skin and how much effort you want to put into washing.
Cotton knitwear
Cotton is generally soft, breathable and less likely to feel itchy. It tends to suit mild days, spring and early autumn, and it is a good layer indoors where the heating is on. It usually holds less warmth than wool.
Wool knitwear
Wool is known for warmth. It traps heat well and copes with cold, damp British weather. Some people find wool itchy on bare skin, and finer wool is usually softer than coarse wool.
Which one for which season?
- Spring: cotton
- Summer evenings: light cotton
- Autumn: either, depending on the day
- Winter: wool, with a tee or thin layer underneath
Does wool always itch?
No. Itch depends on the fibre and how fine it is. If you are unsure, wear a thin tee underneath, or touch the fabric against your neck or wrist in the shop before buying.
How do you care for each?
Always read the label first, because it overrides general advice. As a rule, cotton is usually easier to wash. Wool generally prefers cool water, gentle handling and drying flat. Our guide on how to wash a knitted hoodie covers the basics, and the same patience applies to most knits.
What about blends?
Many knits mix fibres to balance softness, warmth and cost. The label lists the percentages, so check it. A blend can be a sensible middle ground if you want some warmth without going all in on wool.
Which should you buy first?
If you wear one knit all year, pick the one that suits the months you feel the cold most. If you own a few, cotton for mild days and wool for cold ones covers you. Think about how often you will wear it too, as we explain in cost per wear.
