The easy way in
Four pairs.
Half a week, sorted.

Why a 4-pack first?
Because four pairs is the smallest amount that lets you actually test it. Wear one to Pilates and the supermarket. One under jeans. One under work pants. One under the dress you're not sure about. Run them through a wash, a wear, and a long day. By the end of the week you'll know whether this is the underwear you've been looking for.
If it is — and 94% of the 150 women who've reviewed it say it is — you'll come back for the 7-pack. Most do. We've found that women aren't loyal to underwear brands until they find one worth being loyal to. We think this is that one.
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 through the day. No mid-morning adjusting, no bathroom-mirror 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. You stay dry, you stay comfortable.
Four colours to pick from
Mix and match across the four pairs in your pack — or commit to one favourite.
Classic Black
Workhorse. Pairs with everything dark.
Midnight Blue
Less harsh than black. Great under denim.
Pastel Pink
The white-jeans pair. Disappears under pale fabrics.
Powder Blue
A soft neutral. Works under most skin tones.
What women actually say
Pulled from verified Judge.me reviews. Read all 150 →
"Very comfortable and 100% seamless. I can wear it with anything and not have to worry about lines or discomfort. Would highly recommend gym girlies and even non-gym girlies to buy this!"
"Love my Gym G's now for my workouts. They stay in place, are comfy where we need it most and have the barely-there look and feel. Very happy."
"Perfect for under gym wear as you can't see them! Would definitely recommend!"
Designed for movement.
Made to forget.
It's called The Gym G because the founders built it to solve the things that go wrong when you sweat, run, twist and bend in underwear that wasn't designed for any of that. Recycled nylon that wicks. A cotton gusset where it counts. Flat seams that don't dig in. Edges that don't roll.
When you fix all of that for movement, you accidentally fix it for everything else too. Most of our customers don't wear it to the gym. They wear it to work, to Pilates, to dinner, to the airport, to the school pickup. The performance is what makes the comfort real — and the comfort is the only reason most women keep reaching for it.
The fabric
Engineered, then softened.
The main body is 73% recycled nylon (from old fishing nets and pre-consumer waste, GRS-certified) plus 27% spandex for stretch and rebound. The gusset is pure cotton because skin is happier next to cotton, full stop. No mystery fabrics, no greenwashing — just the right material in the right place.
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.
| Size | AU dress | Hip (cm) |
|---|---|---|
| XS | 6–8 | 85–90 |
| S | 10 | 90–95 |
| M | 12 | 95–100 |
| L | 14 | 100–106 |
| XL | 16+ | 106–112 |

Care (so they last)
Treat them well and these aren't a "buy them again in 6 months" purchase. They're a year-plus piece of underwear.
Questions worth asking
What if I don't love them?
Underwear is one of the few things we can't accept back for hygiene reasons — but if there's a fault or sizing issue we'll always make it right. Email hello@barethrills.com within 14 days and we'll sort it.
Will the discount apply automatically?
Yes. When you build a 4-pack with the picker below, the $29 saving is applied at the cart automatically — you don't need to enter a code.
Can I mix sizes within a pack?
Absolutely. Each pair has its own size + colour selector. Buy three M and one L, or four different colours, or all the same — your call.
How long do they last?
With the wash care above, comfortably a year of regular wear before the elastic starts to soften noticeably. We've had customers come back for a refresh after two years.
Do they really not show under leggings / white jeans?
Yes — that's the whole design. Bonded edges, flat waistband, no seams to print through. Pastel Pink and Powder Blue do best under pale fabrics; Classic Black under thicker / darker.
Where do they ship from?
Australia. We ship to most countries via Australia Post — free on every multipack.
Sustainability
Recycled, certified, intentional.
The recycled nylon body is PRUECO® — sourced from old fishing nets and pre-consumer textile waste, then certified by the Global Recycled Standard (GRS). It means there's a paper trail, not just a marketing claim. Every pair you wear keeps that material out of landfill and out of the ocean.
A small Australian team
Quietly making one thing well.
Bare Thrills is run by a small team based across regional NSW and Sydney, focused on a single product done properly. We started because we couldn't find underwear that disappeared under everything we actually wore — and now there's a growing list of customers saying ours is the only underwear they buy.
