Is Merino wool itchy against bare skin?

Extra-fine Merino is much softer than standard wool, and most people wear it directly over a shirt or tee without irritation. Sensitive skin may still prefer a base layer underneath.

How should I wash it?

Use a wool cycle or hand wash in cool water with a wool-safe detergent, then dry flat. Avoid hot water, tumble drying and hanging, which can stretch or shrink the knit.

Is it warm enough on its own?

It works as a mid-layer in cool weather and as an outer layer on mild days. It has no windproofing, so in cold wind you will want a shell over it.

Does it fit under a jacket?

The interlock knit is denser than a thin sweater, so it adds some bulk. It layers well under roomier coats but can feel snug under a slim-fitting shell.

Merino knits can pill where there is friction, mainly at cuffs, underarms and where a bag strap rubs. Washing inside out and avoiding rough surfaces limits it.
