When Should You Replace Your Underwear? The Signs of Wear

Short answer: Underwear should be replaced when the elastic has gone slack, the fabric is worn thin or the shape is gone, and for most people that happens after one to two years of daily wear. Worn-out underwear fits badly, chafes and does its job less well, so replacing it is money well spent.

The five clear signs of wear

A slack waistband, see-through or thin fabric, holes at the seams, baggy legs and a shape that does not recover after washing. If you see two or more of these signs, it is time to replace them. See the current range under bamboo underwear for men.

How to make your underwear last longer

Wash at 30 to 40 degrees, avoid the tumble dryer and skip the fabric softener. Elastane cannot handle high heat, and it is usually the elastic that gives up first. Follow our washing guide for bamboo clothing and you will noticeably extend their life.

Quality pays off over time

Underwear in good bamboo viscose keeps its shape and softness through more washes than cheap alternatives, so the cost per wear often ends up lower. Read the maths in the post about bamboo and economy, and find the right fit with the guide to bamboo underwear for men.

Frequently asked questions

How long does a pair of underwear last?

With daily wear and correct washing, typically one to two years. Quality, rotating between several pairs and gentle washing can extend their life.

What wears out first on a pair of underwear?

Usually the waistband elastic, which loses its stretch from the heat of washing and tumble drying. After that come thin fabric and baggy legs.

Can I extend the life of my underwear?

Yes. Wash at a low temperature without fabric softener, skip the tumble dryer and keep enough pairs in rotation so each pair is washed less often.
