Amber 運動丁字褲

Did three hundred burpees in these and forgot I was wearing them. The fabric stays smooth against the skin, no bunching or sliding around, and the waistband has actually stayed put through every single rep.

The bonded waistband is the real winner here—it doesn't roll or dig, even through a full leg day. I've washed it a bunch and it hasn't stretched out or lost its shape, which is rare for a thong this smooth.

Three months of daily gym sessions and these haven't rolled or slid once, even during heavy deadlifts. The bonded waistband is practically invisible under leggings, which I was a little skeptical about at first.
