No panty line. No leaks. No one needs to know. The Invisi Seamless G-String is your go-to for fitted clothing, gym tights, and activewear. Bonded flat seams sit flush against skin with zero digging in — completely undetectable under anything you wear. Designed for light days: spotting, discharge, the tail end of your period, or as backup to a tampon or menstrual cup. If you're comfortable in a G-string normally, this feels exactly the same — just with quiet, built-in protection. Why you'll love it: Seamless bonded construction — no visible panty line under fitted clothing Lightweight and barely-there feel for all-day comfort Absorbent gusset for light flow, spotting, or discharge Works as standalone protection on light days or as tampon/cup backup Perfect under gym tights, activewear, and form-fitting outfits Fabric: Inner gusset: 95% cotton / 5% elastane (note that some of our old stock is mislabelled as polyester inner but it is actually 95% cotton, if you receive those anomolies please do not worry, its a misprint). Outer: 78% nylon / 22% elastane Seamless bonded seams | Light absorbency | PFAS-free | No VPL
