No leaks, no mess, no worries. First Line is here to keep you dry and on the go (or on the couch).

With built-in leak protection for light days and incontinence, you’ll be able to rest, move, and breathe easy. Our trunks feature a floating gusset that can fit a pad with wings for some extra coverage when you need it. And hey — they’re antibacterial and odor-repellent, all while looking and feeling just like your favorite Tomboys. Plus, the outside fabric is also leak resistant for even more protection.

First Line underwear is made with OEKO-TEX® 100 Certified fabrics which are free from chemicals that are toxic to humans including PFOS and PFOA chemicals that have been shown to cause infertility or cancer. Learn more.
