UnderSwim: Period Swim Underwear (G-Fit)

PERIOD STRESS UNDER A HIGH-CUT SWIMSUIT? Hard pass.

UnderSwim G-Fit is period-proof swim underwear designed to disappear under high-cut swimsuits, racing suits and bikini bottoms.

Its seamless high-leg cut gives you a discreet layer beneath the swimwear you already want to wear.

Up to 15 ml absorbency is around two tampons’ worth of protection, without bulky seams or a waterlogged feel.

A water-resistant outer helps keep pool and sea water out. Four thin absorbent layers lock menstrual flow in. No wet-nappy energy.
