We recommend wearing the underwear up to 8-12 hours for maximum protection. It is important to emphasize that the use of each style varies depending on the use you give it, your flow and your own preference. If this is your first time wearing Nudah Basics, we recommend checking every 3-4 hours if you still feel comfortable and dry. We recommend that you try our different styles and see how long each one accommodates you for different moments and needs.
