How long does a pair of knickers last

Short answer: A pair of briefs usually lasts one to two years with normal use. It is the elastic in the waistband and leg openings that gives way first, not the fabric itself.

The elastic sets the limit

Elastic loses tension with every wash and every day of wear. It is stretched each time you put them on and works all day to keep them in place. After many rounds the waistband loosens and the leg openings start to stand out. This is where a pair first feels worn. See bestsellers from Copenhagen Bamboo.

The fabric outlasts the elastic

A knitted fabric can easily last three years without thinning. The fabric has no tension to lose the way elastic does, and it wears slowly with normal use. That is why many pairs still look fine long after the waistband has gone slack. See bamboo sweat for men and women.

Washing and heat speed it up

High temperatures and tumble drying halve the life of the elastic. Heat takes away its stretch much faster than normal wear, and the dryer drum pulls and twists the edges. Wash at forty degrees and let them air dry. Those two things make the biggest difference. See men's bamboo sweat.

Signs they are worn out

The clearest sign is a waistband that rolls down or no longer lies close to the skin. Leg openings that stand out or fold are another. If the fabric is still whole but the elastic is slack, the pair is near its end. It rarely feels as good again, however it is washed.

More pairs in rotation

The more pairs you have, the fewer times each one is washed and stretched. With only a few pairs, they go in the machine several times a week and the elastic wears faster. In rotation, wear spreads out. Put freshly washed pairs at the bottom of the drawer so all are used evenly.

A laundry bag protects the edges

In a full machine, elastic and edges can catch on zips, hooks and buttons on other clothes. A laundry bag keeps the briefs together and shields them from that. It helps most when they are washed with trousers and jackets. Turning them inside out is a good idea too.

Air drying is the safe choice

Briefs are small and dry quickly on a rack or a peg. There is rarely a good reason to put them in the dryer. Air drying spares the elastic from heat and movement entirely, and it is the easiest way to give a pair a longer life without extra effort.

Do not stretch them more than needed

Elastic wears every time it is fully stretched. Put them on and take them off without pulling hard on the waistband, and do not wring them when wet. Wet elastic is more fragile than dry, and a hard twist can take some of the stretch at once. Press the water out between your hands.

Frequently asked questions

How long do briefs last

Usually one to two years with normal use. The elastic gives way before the fabric does, and the waistband loses its grip first while the rest still looks fine.

What wears out first

The elastic in the waistband. It loses tension with every wash, while the knitted fabric itself can often last another year without thinning.

How do you make them last longer

Wash at forty degrees and avoid the dryer. Heat is what takes the stretch out of elastic fastest, so air drying makes a big difference.
