Yes, products made from Merino wool can form lint or pilling, but this is often less likely compared to other types of wool. 

However, lint or pilling, as some also call it, has no impact on the functionality of the product and is often easily removed with your hands or a small specialised comb for this purpose.

Lint occurs when short fibres detach from the surface of the fabric and form small lumps. However, Merino wool has some natural properties that reduce the risk of linting. For example, merino wool has very fine and long fibres, which makes it softer and less prone to loose fibres. In addition, merino wool is naturally elastic, which means the fabric can stretch and return to its original shape, reducing wear and helping to prevent linting. 

Modern treatment processes like superwash treatment also make the fibres smoother and less likely to tangle and form lint. Although Merino wool is generally less prone to linting, it can still happen with frequent use and washing. To minimise the risk of lint, it's a good idea to follow the washing instructions carefully and use mild wool detergent.
