Best 2025 purchase

I recently received the V2 Seamless Anti-Slip G-String, and instantly realised how amazing they are! Sizing is accurate, and they fit comfortably on your skin. The material is better than previous seamless undies I’ve owned (& I’ve tried a lot)! And my favourite part.. honestly unnoticeable under clothes, & bike shorts! Major anxiety of adjusting down stairs gone!

Grabbing another pair now, so worth it!!

Good quality but the new style doesn’t fit. Was a size M in the old style and the M in the V2 is so uncomfortable. Preferred the higher waist. Wont wear these again & have purchased from a different company.

Hey Molly,

Thanks a bunch for taking the time to share your thoughts!

The new V2 design is intentionally smaller and features a lower rise compared to our original version. This allows them to sit lower, for example, under leggings. While the fabric is still our original buttery soft, coffee-made-fabric it does require a bit of time to give. We generally recommend sizing up from your V1 size; for instance, if you were a size M in V1, you'd likely be a L in the new style.

We totally get that everyone has their own perfect undie vibe, so we really appreciate you being so honest with us. Your feedback is super helpful! 😊

My favourite undies!!

After a long search for good quality undies- I’ve found them !! Put them to the test teaching 4 hot mat Pilates classes & by the end still no creases, sweat marks or camel toes !! Comfiest and softest pair yet xx

Perfect for Pilates!

Comfortable, breathable and great quality! 🤍

Frequently Asked Questions

General Questions

What are Subtldays made from?

Coffee: Our Zero Cheeky Slips G Sting is made from recycled coffee beans(67% Nylon 33% Spandex) that is breathable, sweat wicking, cooling, and odour resistant. It includes a bamboo gusset infused with mint fiber to maintain a cooling effect.

How is it front wedgie/camel toe proof?

Our underwear includes a thicker gusset made of a microfibre spacer that moulds to the body, and prevents an unwanted front wedgie whilst wearing activewear or leggings.

How do I wear my Subtldays?

Our Zero Cheeky Slips G-String look and feel just like your normal underwear, but can effectively prevent an unwanted front wedgie.

Do they feel bulky?

They will be thicker in the gusset than your average underwear, however are still lightweight and undetectable.

Where is your company based?

We’re based in Melbourne, Australia.

Is there odour or dampness?

Our underwear has a cooling feeling with mint fibre in the gusset, which has also undergone excellent deodorant property testing, whilst the main fabrication of coffee fibre has the same deodorisation effect as bamboo charcoal fibre. It can effectively control the body’s surface moisture, is rapid drying and bacteria free.

Are your underwear anti-bacterial & odour free?

The microporous structure of our underwear control moisture that inhibits bacterial growth and make the fabric odour-free

Are they machine washable?

We would recommend popping your Subtldays in a delicate wash (best practice to use delicates bag) or hand wash (cold setting). DO NOT use fabric softener as it can block and prevent the moisture wicking and anti-microbial technologies from working.

How to Care for Subtldays

Do I need to pre-wash them?

Yes, although not entirely necessary (nothing bad will happen if you don’t!). We recommend giving your underwear a quick rinse and a machine wash before wearing on your hoo-ha.

How do I wash them?

We recommend rinsing thoroughly by hand first, then pop in a delicate wash (best practice to use delicates bag) or hand wash (cold setting). DO NOT use fabric softener as it can block and prevent the moisture wicking and anti-microbial technologies from working.

Can I put my Subtldays in the dryer?

We do not recommend putting your Subtldays into the dryer, as you are unable to control the temperature of a dryer once the machine is running, even on a low heat setting it is still unknown what that temperature could be. Excessive heat can compromise the shape, and front-wedgie proof technology.
