• Patented bonded edges help prevent against side leaks.
• The carbon cotton gusset top layer wicks away moisture from your skin.
• These underwear feature our signature buttery soft fabric.
• No show construction is designed to be invisible under clothes, including workout leggings.
• Machine washable just like regular underwear.
Our original leakproof technology is perfect for everyday wear (think sweat, discharge and light leaks), backup protection during heavier days or on its own for lighter days.

• Medium hip & bum coverage
• Thin, built-in liner, 7.5-8.5” long

I am a loyal Knix shopper for the light leakproof bikini. Fits comfortably, love the fabric. My first round started to wear out around 3 years, but some from my original batch are still in great condition.
