What you'll notice on day one

Three things customers tell us within the first wear.

It stays put

The waist sits flat where you put it. The leg openings don't shift. No mid-morning rescue mission in a bathroom mirror.

It's invisible

No lines through white pants, no bumps under a dress, no bunching anywhere. Truly disappears under everything.

It stays dry

Pilates, a hot day, a long flight — recycled performance fabric wicks moisture without holding it.

Watch the proof

Dries faster than cotton. Way faster.

Recycled performance fabric wicks moisture and dries in a fraction of the time of cotton or bamboo. A hot day, a long flight, a Pilates class — you stay comfortable.

Slide for the timed dry-test next to a cotton thong.

Why your G-string digs in - and what actually fixes it

Digging in isn't a personality trait of G-strings. It's a construction problem, and occasionally a sizing one. If your underwear leaves marks on your hips, or you're aware of the waistband by 10am,...

Best underwear for reformer Pilates - Bare Thrills

Best underwear for reformer Pilates (from people who actually do it)

Reformer Pilates is uniquely brutal on underwear, and nobody warns you. It's not the sweat — a reformer class barely breaks one. It's the positions. You spend half the class lying down, bridging, o...
