The thong you love—now with more comfort, more stretch, and an even better fit. Designed with a triple-layered front panel and our new high-performance 4-way stretch fabric, this mid-rise tucking thong delivers a smoother, more secure tuck that moves with you.

Perfect under leggings, dresses, or tight-fitting outfits where pantylines are a no-go, it gives you a seamless look and lasting comfort all day long. Our upgraded compression fabric provides the ideal balance of firm hold and breathable ease, with moisture-wicking, quick-drying, and odor-resistant technology to keep you fresh, confident, and comfortable—no matter what you wear it under.

Fits true to size, we recommend the size you'd wear in non-tucking underwear.

Edward Z. ★★★★★

The triple-layered front panel lies completely flat under jeans and holds its shape even after a full day of errands. I wore it for a long commute, and the mid-rise cut never rolled or pinched, which is something I've struggled with in other tucking underwear.

Violet X. ★★★★★

The 4-way stretch fabric moves with me better than any other tucking underwear I've tried—no bunching or riding up even after a full day at work. Mid-rise sits right where I need it, and the triple layers stay put without feeling bulky.

Natalie N. ★★★★★

The triple-layered front panel finally gives me the smooth, flat look I’ve been chasing without any readjustment panic. The 4-way stretch moves with me through a full workday, and it actually stays put during my commute.
