Light leggings show everything. A regular thong shows its edges, and a thin front shows the rest. This thong fixes both at once.
The wide front gusset keeps the front smooth, and the invisible edges disappear under even the tightest fit.

Seamless construction and flat edges glide under high-waisted leggings, so nothing shows, even in deep lunges and bridges.
It works under jeans, work pants and a fitted dress too. No line, no ridge, no wedge.

The fabric is silky soft with 4-way stretch, lightweight and ultra-breathable, so it moves with you from the morning meeting to the evening workout.
It wicks sweat away, so there are no sweat patches and no clinging fabric after a hard session.

Four details, all doing one job: keeping you smooth and comfortable under anything you wear.

Silky soft, lightweight and ultra-breathable, with 4-way stretch.

Flat, seamless edges that leave no lines under fitted clothes.

A wider front panel that keeps the front smooth, so there is no camel toe.

A high-rise waistband that stays flat and secure all day.
Gym, office, date night. Anywhere your clothes fit close.
