Airing instead of washing

Sep 12, 2026

Short answer: Outer layers such as sweatshirts and jumpers can be aired several times between washes. Anything that has touched the skin directly should be washed after each wear, because it has absorbed sweat.

What can be aired

Hoodies, sweatshirts and jumpers worn over another layer can be aired between washes. They have not sat directly on the skin all day, so they have not absorbed much sweat. A night on a hanger is often enough for them to smell fresh again. See the styles in men's bamboo sweatshirts.

What needs washing

Underwear, socks and T-shirts worn directly against the skin absorb sweat during the day and should be washed after each wear. Airing only removes odour from the surface, not what sits inside the fabric. That covers everything in bamboo underwear for men.

The layers make the difference

It is the layer underneath that makes airing the outer layer possible. A T-shirt or vest takes the sweat, so the sweatshirt on top stays fresh for longer. If you wear a hoodie directly on the skin, it counts as an inner layer and should be washed more often.

Why airing extends garment life

Every wash wears the fabric a little. The fibres rub against each other in the machine, and the colour fades slightly each time. Airing outer layers instead of washing them after every wear helps them keep their shape and surface. The same goes for all men's clothing you wear often.

How to air properly

Hang the garment on a hanger in a room with air circulation, not behind a closed wardrobe door. Air needs to reach every side, including under the arms. Leave it overnight and check the smell in the morning. If it is still not fresh, give it another night or put it in the wash.

Fresh air outside

You can also air clothes outside on a balcony or in the garden. Hang them in the shade and avoid direct sun, which fades colour. An hour in the shade with a little wind often does more than a whole day in a closed room. Bring them in if the air is damp.

Signs it needs washing

Airing has its limits. If the garment still smells after a night on the hanger, has visible marks or feels damp, it is time to wash it. The same applies if you have sweated a lot in it. Trust your nose and eyes, and wash once too often rather than once too few.

A simple routine

Many people settle on a routine where inner layers are washed after each wear and outer layers are aired between two and five wears. It keeps the laundry basket smaller and saves time and water. The rhythm depends on how active you are and how warm it is.
