Why You’ll Love It
-
Total Peace of Mind: Every set includes our signature BFFs by Knicked. These high-tech, hi-cut briefs are designed to be worn discreetly under your swimwear. They feature a slim, absorbent gusset that locks in leaks without the bulk of a pad or the hassle of a tampon and blocks water.
-
Used for non period days: Can we worn as a gorgeous set without the BFFs

Flattering Hi-Cut Fit: The matching bikini bottoms feature a high-cut leg to elongate your silhouette and provide a modern, comfortable fit that stays in place.
-
Versatile 3-in-1 Tech: Your BFFs aren't just for swimming! Use them for Swim, Dance, and Play. They are the perfect backup for any high-activity day.

"No pads, no tampons, no worries. Just you and the water."
How to wear:
These aren’t your average undies - pull them on, then up high at the sides so they sit snugly and low under the belly for the best protection.
Care tip:
Wash before first use. Each pair comes in a reusable, waterproof, and odour-proof wet bag – perfect for storing your BFFs in your bag or when they’re wet, waiting for a wash. Less waste, more wow.
No leaks. No worries. No limits. Just freedom.
