Owen ★★★★★

These feel so much lighter and less bulky than my old cloth pads, which I really appreciate on heavy days. The 30ml absorbency held up perfectly during a long work day without any leaks. I've already ordered more.

Scarlett ★★★★★

I was a bit nervous about trying period underwear for heavy days, but these feel super slim and secure—no bulkiness at all. The ultra-soft fabric is a nice surprise, and they really do handle up to six tampons' worth without leaking.

Eva H. ★★★★★

The 30ml absorbency handled my heaviest day without a single leak, and the fabric is so thin I forgot I was wearing it. Finally found something that feels like normal underwear.
