What you should know about wash bags

Short answer: A laundry bag protects small and delicate items from tangling with the rest of the wash. It is the cheapest way to extend the life of underwear and socks.

Protects against tangling

Without a bag, socks and briefs easily tangle around zips, hooks and buttons from other clothes in the machine. That is how edges, straps and elastic get stretched and eventually damaged, even during an entirely ordinary wash at a normal temperature. See bamboo underwear for women.

Keeps small items together

Socks placed in a bag do not disappear into sleeves or the back of the machine, as they often otherwise do. That solves one of the most common annoyances of doing laundry, namely the endless hunt for the missing sock after drying. See all bamboo socks for men.

For bras and tights

These two categories tolerate the least mechanical strain of anything you wash, and so they always belong in a bag, no matter how little laundry is in the machine. Underwires can bend and elastic can overstretch if the pieces hit the drum unprotected. See wireless bamboo bras.

Do not overfill the bag

An overfilled bag means the laundry inside does not get properly clean, because water and soap cannot circulate correctly between the individual pieces. Half full is right, even though it can feel like wasting a trip through the machine. See our washing and care guide.

Close zips first

Bags help with most of it, but still close zips and hooks on the rest of the laundry in the machine before you start the programme. Otherwise they can still catch on thin fabrics through the fine mesh and tear the fibres. See bamboo underwear for men.

Choose the right mesh size

A fine mesh protects best against sharp items tearing the fabric, while a coarser mesh gives better water flow and therefore a cleaner wash. For most everyday items, a medium mesh is a good compromise between protection and cleanliness.

Sort by type inside the bag

Do not mix heavy and light items in the same bag, since the heavy ones can press against the light ones during the spin cycle and damage delicate details. A bag with only one type of item protects better than a mixed bag does.

Bags also keep colours apart

A bag can act as an extra barrier against coloured fabric bleeding onto lighter items during the wash, even though it does not replace normal colour sorting. That adds an extra layer of reassurance, especially with new or dark items.

Replace the bag once it wears out

The bag itself wears out over time too, and holes in the mesh make it less effective at protecting the items it is meant to guard. Check the bag regularly, and replace it if the mesh starts tearing or the seams come loose.

Frequently asked questions

What is a laundry bag used for?

To protect small and delicate items from tangling with other laundry during a wash, and from being worn down by hard surfaces inside the machine.

What should always go in a bag?

Bras and tights. They tolerate the least mechanical strain and can be damaged by underwires, zips or spinning without protection.

Can the bag be filled completely?

No. An overfilled bag means the laundry inside does not get properly clean, because water and soap cannot circulate correctly between the pieces.
