What's the difference between a hookless (snap-in liner) shower curtain and a traditional one?

Hookless or 'no-hook' designs use built-in flex rings or a header that slides directly onto the rod, and most of the fabric picks here pair that with a snap-in waterproof liner so you wash the outer curtain and re-clip the liner. Verified-purchase reviewers favor them for fewer parts to lose and a cleaner hotel look, though some note the integrated rings can feel less universal than standard hooks.
