Why Thinx earned a B+
About Thinx
Period underwear was a genuinely new product category when Thinx popularized it, and the brand is still the name most people reach for first when they're curious about ditching pads and tampons. The absorbent-layer technology is the whole draw, and reviewers generally say it delivers on the leak protection promise, though heavier flow days may still need backup. Because it's underwear, you'd expect a strict no-returns hygiene policy - Thinx does the opposite, letting you keep, gift, or donate the pair instead of shipping it back.
That's an unusually generous and low-friction return process for an intimate apparel brand. Anyone looking to cut down on disposable period products, or just wanting a comfortable backup option, is the natural shopper here.
