Women's underwear is uncomfortable, irritating and generally annoying. At Flissie, we believe in creating bamboo underwear that doesn’t just look good, it also feels great and supports the planet. That's why we've created the UK's most comfortable bamboo underwear for women who prioritise feeling confident and comfy all day long.
We designed our comfortable women’s underwear with a pressure-free waistband and smooth seams. If your first pair doesn’t feel perfect, we’ll help you find a better size and send it for free or refund you, no questions asked.
Flissie celebrates every shape and style with eco-friendly bamboo underwear for women. Our mission is to empower women to embrace their bodies while enjoying the softness of sustainable fabrics.
At Flissie, we design our comfortable women’s underwear with all shapes, sizes, and styles in mind. Every pair, whether it’s our classic women’s boxers or our upcoming lines, features anti-chafing seams, a pressure-free waistband and luxuriously soft bamboo fabric. Plus, we stand behind our products with a comfort guarantee: if your first pair isn’t the perfect fit, we’ll exchange or refund it. We also believe in giving back - every 3 pairs sold equals 1 pair donated to support vulnerable women around the world.
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.
