Bamboo Clothing (underwear for all sizes)

Boody offers bamboo undies. Industrial bamboo is not the same as fresh shoots eaten by pandas. It’s not local but the shoots are quick to grow, and it’s comfortable and breathable. This range offers plus-sizing

Also for men.

For more local fabric, The Hemp Shop has a small range, often blended with organic cotton. Also for men

Nearly ALL ‘sustainable undie brands’ use a little elastane (they say it’s for comfort and stretch). For the rest, it’s best to invest in a microfiber filter (which you can to launder all synthetics, then you catch the microplastics to be sent off for recycling, and get empty cartridges in return). 

Where to recycle your old undies!

You likely know that underwear cannot be returned once bought for hygiene reasons. And for the same reason, you can’t donate it to charity shops. But you can drop old pairs (even torn or worn) into textile banks. From there, the fabric gets shredded and turned into industrial products like carpet insulation.
