Why Merino Wool Garments Should Not Be Washed After Every Wear
The first instinct with a wool garment is the same as with a shirt: wear it, take it off, put it in the laundry basket. With Merino, this is a mistake—and not out of laziness. The fiber itself works differently.

Why merino doesn’t get dirty like other fibers
Merino wool has a naturally breathable and partly self-cleaning structure: the fibers repel moisture and retain fewer odors compared to synthetic fabrics or cotton. A garment worn for a normal day, without direct contact with intense perspiration or visible stains, does not need washing. Simply air it out—laid flat or hung, away from radiators or other heat sources—and it will be ready to wear again the next day.
How often should merino knitwear be washed?
There is no fixed number of wears to follow. What matters most is what happened while wearing it: if there was prolonged contact with skin and intense perspiration, if stains appeared, or if the season is ending and the garment is about to be stored, then yes, it should be washed. In all other cases, airing is sufficient.
And here it is worth being clear about one thing: washing it anyway, “just to be safe,” is not a neutral gesture. Every cycle—even delicate, even by hand—stresses the fibers. Merino wool, precisely because it is fine and extrafine, is more affected by friction than coarser wool.
How to wash it when truly necessary
Cold water, detergent specifically for delicate garments. Two actions make the difference between a garment that lasts over time and one that is ruined after the first wash: do not wring by twisting the fabric, but gently press out excess water; and never hang vertically to dry, because the weight of the retained water will distort the garment. Always dry flat.
Pilling on garments: what it is and what causes it
Those small fiber clumps that appear under the arms, on the sides, or where the garment rubs against a bag or belt usually say nothing about the garment’s quality. They come from repeated friction—against other fabrics, against itself, against something touched every day—and it is a phenomenon that affects any fine worsted wool, not a manufacturing defect.
They can be removed with a fabric comb or lint remover, gently passing it in the direction of the knit. If they return quickly in the same spot, often the cause is not the garment: it is the bag always carried on the same shoulder, or the belt rubbing in the same place with every step.
Minimal care is what matters
Fewer washes, more attention to how it is dried and stored. These are the same principles we explain on the Garment Care page, where you will also find specific instructions for the Cashmere and Mohair lines.
A Morgano garment is designed to last through more seasons than one would normally expect from knitwear—provided it is allowed to breathe between wears, rather than rushing to wash it every time.
