Bobbles on the chest of the top

Short answer: Pilling appears where the fabric rubs against something all day. On the chest the cause is usually a bag strap or a harness, not the quality of the fabric. The pills can be removed in a minute, and there is a lot you can do to stop them coming back.

Friction is the cause

Pills form where one piece of fabric rubs against another again and again. Small fibres loosen from the surface, twist together and stay there as tiny balls. It happens faster in soft fabrics because the fibres are fine. So it is not a sign of poor quality, but a sign of where the top gets the most wear.

The bag strap is the most common source

A strap across the chest sits in the same spot for hours and moves a little with every step. That is exactly the kind of rubbing that causes pilling. If you carry a crossbody bag or a backpack with a chest strap every day, you will see it on your tops first. This also applies to bamboo t-shirts for women, where the fabric is thin.

Switch sides with your bag

The easiest way to reduce the problem is to switch shoulders. When the strap sits in a different place from day to day, the rubbing spreads over a larger area and no single spot gets worn down. It sounds like a small thing, but it makes a clear difference over a few weeks. Also try carrying the bag over a jacket when the weather allows.

Remove them with a fabric shaver

A cheap fabric shaver removes pills in a minute without harming the fabric. Lay the top flat on a table, hold the shaver lightly against the fabric and move it in small circles. Do not press hard, or the blade can catch the fabric itself. It works on thin tops as well as on a thicker bamboo sweatshirt for women.

Do not pick them off with your fingers

It is tempting to pull the pills off one at a time, but that drags new fibres out of the fabric. The result is more pills in the same place and a thinner fabric. A fabric shaver or a lint comb cuts the pills off instead of pulling them. It is gentler and takes less time.

Wash inside out

Washing inside out reduces friction in the machine, because the outer side does not rub against the drum and the rest of the laundry. Use a gentle programme and a low spin. This matters most for thin pieces like bamboo tops for women, where the surface is extra fine. Close zips and buttons on the other clothes before washing too.

Do not wash with rough materials

Jeans, towels and clothes with velcro or metal parts wear on soft fabrics in the wash. The rough surfaces act like sandpaper on the fine fibres and cause pilling before the top has even been worn much. Wash the soft pieces in one load and the rough ones in another. That way both last longer.

The tumble dryer wears fabric too

In a tumble dryer the laundry turns for a long time and rubs against itself and the drum. That gives the same kind of wear as a bag strap, only across the whole garment. Air drying is therefore the gentlest choice. Hang the top over a rail or lay it flat on a drying rack, and the surface will stay smooth much longer.

Frequently asked questions

Why does pilling appear on the chest

Because a bag strap or harness rubs the same spot for hours, every single day the top is worn. The rest of the garment gets far less friction and stays smooth.

Can pills be removed

Yes. A fabric shaver does it in a minute, and the fabric is not harmed as long as you hold the shaver lightly against the surface and do not press.

Can pilling be prevented

Partly. Wash inside out, switch shoulders with your bag, and avoid washing the garment with rough materials like jeans and towels that wear on the fabric.
