Stays Dry

Disappears Under Everything

Recycled Fabric

Stays in Place

Underwear you forget you're wearing.

The Gym G is built for the day you don't change clothes — Pilates in the morning, eight hours on your feet, dinner that runs late. The kind of day where the wrong underwear becomes the only thing you can think about by 3pm.

Solving that problem started with athletes — no scrunching, no sweat-through, no visible lines, no migration. Solving it for everyday wear was an accident. Most of our customers don't wear it to the gym. They wear it everywhere, because once you've worn underwear that genuinely disappears, going back to anything else feels like a step down.

What you'll notice on day one

  • It stays put. Flat waistband, leg openings that don't shift. No mid-morning rescue mission in a bathroom mirror.
  • It's invisible. Bonded edges, no internal seams to print through. Disappears under white pants, leggings, slip dresses, denim — everything.
  • It stays dry. Recycled performance fabric wicks moisture without holding it. Hot day, long flight, hot Pilates — you stay comfortable.

The fabric

  • 73% recycled nylon (PRUECO® — sourced from old fishing nets and pre-consumer waste)
  • 27% spandex for stretch and rebound
  • 100% cotton gusset because skin is happier next to cotton, full stop
  • Global Recycled Standard (GRS) certified — paper trail, not just a marketing claim

Sizing

Designed to be firm from the very first wear — the buttery soft fabric only gets softer with each wash. If you're between sizes, size down.

  • XS: AU 6–8 (hip 85–90 cm)
  • S: AU 10 (hip 90–95 cm)
  • M: AU 12 (hip 95–100 cm)
  • L: AU 14 (hip 100–106 cm)
  • XL: AU 16+ (hip 106–112 cm)

Care (so they last)

  • Cold machine wash
  • Air dry only — no tumble dryer
  • Wash before first wear

Treated this way, these aren't a "buy them again in 6 months" purchase. A year-plus piece of underwear.

Why women keep coming back

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 through the day. No mid-morning rescue mission at 3pm.

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. Hot day, hot Pilates class, long flight — you stay comfortable.

Real women, real wear.

If something's off, we make it right.

We can't accept underwear back for hygiene reasons — but if there's a fault, sizing issue, or anything else that's not right within the first 30 days, email hello@barethrills.com and we'll sort it. Most customers actually reach out wishing they'd ordered the bigger pack.

Comfort or performance? why not have both 🤷
