Not quite as comfy as I hoped

I love the Hello Cup so I was really excited to try these! Unfortunately, they're not as good as I hoped they would be. I'm not a fan of the material used - it feels very synthetic, like a swimsuit. It was comfortable to wear and seems to have good absorbency, and it's AWESOME that it can be machine dried, but I think I'll stick with more breathable alternatives that feel like cottton.

The Hello Cup

Hello Undies are made from 78% polyamide, 22% elastane for fit and longevity. We really want our customers to be able to get A LOT of use out of their Undies and this fabric will definitely last! The fabric is smooth and allows for a snug fit for best performance. It feels quite different to cotton so you would definitely notice a difference in the feel of the fabric. We're really glad to hear that you found them comfortable and absorbent! Love from team Hello Period xx

Best freedom ever

I love these knicky noos. Not only do they provide me with fantastic period freedom, and feel great, but if my cat curls up in my lap and is extra snuggly and cute, i dont have to worry about lbl since going ***** isnt an option when cats are comfy. I also feel good about not having to use pads, not having to think about where my pads are, or descreetly disposing of pads. They feel great, easy to care for and fit perfectly (undies, not cat)
