最後機會三角褲（藍色）

These are the softest underwear my son owns, the modal fabric feels like it breathes better than his cotton ones. He's been wearing them for a week and there's no bunching up or digging in.

The blue color is even richer in person, and the stretchy spandex keeps its shape after a dozen washes without sagging at the waist. My son actually asks for these over his other pairs, which says a lot.

My son actually asks for these by name now, which is a first. The modal blend stretches just right during his endless somersaults without losing its shape after a week of washes.
