What to expect from bamboo period pants
Short answer: Period underwear with bamboo is reusable underwear with an absorbent layer in the gusset. With proper rinsing and gentle washing it can be used many times, but the absorbent layer and the elastic age over time, and it should be replaced once it no longer performs as before.
How it is made
Period underwear looks like ordinary underwear but has several layers in the gusset. The innermost layer sits against the skin and may be made from bamboo viscose, which feels soft. Beneath it is an absorbent layer, and on the outside there is often a membrane that prevents leaks. How much it can hold depends on the style. Follow the manufacturer's guidance on how long it can be worn. See period underwear.
Rinsing and washing
Period underwear should be rinsed in cold water after use until the water runs fairly clear. Warm water can make blood set. It is then washed in the machine at the temperature on the label, often 30 to 40 degrees, ideally in a laundry bag. Use a mild detergent without fabric softener, because softener can coat the absorbent layer and reduce absorbency. Always follow the manufacturer's care instructions, as they can differ between styles.
Drying
Period underwear should be air dried. The tumble dryer and radiators can damage the membrane and the elastic. The absorbent layer dries more slowly than the rest, so hang the pants with the gusset open to the air. Put them away only once they are completely dry. Many people keep several pairs, so there is always a clean, dry pair ready when needed.
What changes over time
After many washes the absorbent layer can become slightly less effective, and the elastic at the edges can loosen. The fabric against the skin may also take on a duller surface. It happens gradually. Pay attention to whether the pants last as long as they used to. If that changes, it is time to consider new ones. Brands such as Boody usually describe the care their styles need.
Skin and comfort
Period underwear is worn close to the body for many hours, so it matters that it feels comfortable. Change it as needed and as the manufacturer advises. If you notice irritation, itching or other discomfort, change style or how you use it, and talk to your doctor if it does not settle. If you have questions about your period, your doctor is also the right person to ask.
When to replace it
Period underwear should be replaced when it no longer prevents leaks, when the elastic no longer sits properly, or when the fabric turns thin. How long it lasts depends on how many pairs you have, how often they are worn and washed, and how they are dried. See also styles from Lindbergh.
