These trunks from Superbottoms are made from 60% modal and 40% cotton. This special blend makes it ultra-breathable and a sweat absorption master. The stretchy fabric allows movement without causing any hindrance. It is thoughtfully designed and causes no irritation on account of scratchy labels or elastics touching the skin. They feature printed details using Azo-free safe dyes. Even the stitches are of a special interlocked design to be minimally intrusive.
