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.
Buy a multipack and save
Singles work, but the maths gets a lot nicer in a pack. 4-Pack — $119 · 7-Pack — $179 · 10-Pack — $219 (save 48%). Free shipping on every multipack. Each pair: your size, your colour.
Designed in Australia. Run by a small team across regional NSW and Sydney. Ships globally via Australia Post.
SIZE GUIDE
The Gym G is designed to be firm for ultimate support during your workouts.
Our underwear is true to size and supportive from the very first wear.
If you are between sizes, we recommend sizing down for the designed supportive fit.
Example: If you are a size S-M (10-12) choose a size SMALL.

RETURN POLICY
Have you ever tried on underwear at a store before you bought them? I think we can agree that underwear is a piece of clothing you'd rather not wear if someone else has! For this hygiene reason we do not offer exchanges. Please read the sizing chart carefully before buying, or contact us if you really aren't sure and need some expert advice on sizing!
Faulty item
As a small business we check and pack each order with love and care to ensure you are receiving exactly what you ordered - the best pair of workout underwear! However, in the event that you do find a fault or damage to your underwear, please email hello@barethrills.com as soon as you receive the item or the fault occurs so we can organise a replacement free of charge.
In your email please include:
- your order number
- clear photos of the fault
- a description of the fault
Please note that we may need to personally assess the fault. If asked to return the underwear they must be unworn and in original condition.
In accordance with the Australian Consumer Law, our policy lasts 30 days. If 30 days have passed since your purchase, unfortunately we can not offer any refunds or replacements on faults.
Of course if you are absolutely LOVING your new underwear we want to hear about it! Email Hello@barethrills.com and let us know.

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.
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 🤷

Quiet underwear. (The compliment we keep getting.)
Underwear that doesn't pull, dig, ride up, hold sweat, or ask for your attention. For anyone whose nervous system is tired of negotiating with their own clothes.
