Sustainability & Ethical Sourcing

We believe that creating the most comfortable women’s underwear starts at the source. That’s why we use bamboo underwear fibres grown with minimal water and no harsh chemicals, helping to protect our planet’s precious resources. Our ethical supply chain ensures fair wages for workers and responsible manufacturing processes from start to finish.

But our commitment to sustainability doesn’t stop with the product itself. Each pair of Flissie underwear is individually packaged in corn starch PLA and we ship orders in sugar cane mailer bags, both of which are compostable. By choosing Flissie, you’re not just investing in bamboo underwear for women; you’re supporting a healthier ecosystem and ethical craftsmanship every step of the way, from fabric sourcing to final packaging.

Exactly what i was looking for

The fit is perfect and it is very comfy. I went for a nude colour to hide under linen pants and it does exactly that. Would purchase again

Really great

Love them want to buy more but never jn Stock

Great fit

Needed something comfortable to wear to stop chaffing between my legs. My daughter recommended these. Also wanted a plain light colour so not to show through clothing. I was concerned about the elastic that covers my belly button as I sometimes have soreness there, but so far so good, no issues. Also other concern was the length of the legs as I am only 5’1”. They hide nicely under shorts. Overall really pleased with them

Very comfortable!

Love these boxers - they’re so comfortable, and the quality is superior to other similar brands I’ve tried! Thank you!

Best purchase

I’ve been wearing Flissie boxers for a week now and will never go back! I’m out walking a lot and needed something that would keep me cool and prevent the dreaded chub rub. I cannot fault Flissie on their wonderful products and will definitely be purchasing more in the future
