We're changing the gusset game
For too long, gussets (you know, that internal lining that gets up close and personal with your intimate parts) have been too short and not given you enough coverage. At the Underdays, we worked with a gynecologist to change the gusset game. We added length and swapped cotton for breathable bamboo to keep you fresh throughout the day and prevent unwanted infections.
