Watch our side-by-side comparison video to see the design the features and benefits we know matter most to girls when they're swimming, training, racing or spending long days at carnivals.
From how the outer fabric behaves in water to how the absorbent layer responds to flow, this short reel shows why not all period swim underwear is created equal.
In our side-by-side test, the comparison pair took on water quickly, while UnderSwim kept droplets on the surface for longer. That matters because water-resistant outer fabric helps resist waterlogging, reduce drag and support a lighter feel in the pool.
When we tested the absorbent layers, the comparison pair held liquid beaded on top before it slowly worked through.
UnderSwim absorbed more quickly, helping draw flow in sooner and lock it into a wider absorbent zone.
UnderSwim was designed with high-performance absorption and a technical weave that helps lock flow down while keeping a lower profile under swimwear.
Compared with thicker poly-fibre combinations that can break apart, clump and create visible bulk, the result is a smoother, more discreet feel under bathers.
Absorbent coverage is one of the biggest differences between the two.
UnderSwim features a wider absorbent zone for more considered coverage and confidence, especially when girls are moving, diving, racing or spending long stretches in the water.
Seam construction can make a surprising difference under swimmers.
Where rigid, pointy seams can rub, chafe or feel bulky, UnderSwim uses smooth bonded seams that flex and move more comfortably with her body.
