Get ready to wear your superhero pants under your clothes!

Our ChiChi Brief is a shape shifting, high waisted bikini brief that will hold you tight in all the right places. 

Her thick, firm waistband means she’ll have your back (and your tummy) on those days when you need to hold it together without feeling held back. 

Sitting at the natural waist and high cut around the leg, our girl ChiChi is perfect for creating a seamless look. She’ll keep you cool as a cucumber in our signature blend of textured and smooth eco fabric, delivering a level of tension and comfort that will have you feeling safe and sexy, all at the same time. 

She’ll support and flatter you and, like all of the nat’v range, she’s super soft - but she’s certainly no softy. These knickers have a very firm waistband by design so size up for extra comfort, and if firm undies are not your bag, baby, you might want to try a different style.

Purpose: Wear better quality underwear that is better for you + planet
Impact: 80% Biodegradable, less carbon and water waste

Style: High-waisted shape shifting bikini brief 
Wear me: Perfect for every day 
Material: 80% Lenzing Tencel, 20% Elastane and Polyamide

Choosing nat’v is a decision that minimises your impact on the environment. Our authentic producer of TENCEL™ Lyocell fibres used in nat’v knickers have a commendable reputation for their environmentally responsible closed-loop production process, which transforms wood pulp into cellulosic fibres with high resource efficiency and low environmental impact. This solvent-spinning process recycles processed water and reuses the solvent at a recovery rate of more than 99%. The material has been carefully selected for its minimal footprint on both carbon and water resources.

Tip 1: Treat me delicately!
nat'v basics are made from delicate, natural fibres so place them inside a delicates wash bag, with similar colours, and they’ll love you back for even longer.
Pre-rinse your leak proof Comforts in cold water until the water runs clear.

Tip 2: Warm and gentle wash.
Imagine Goldilocks was putting your wash on - not too cold, not too hot, warm and gentle is just right.

Tip 3: Mild detergent, no harsh chemicals.
These babies are already super soft, so you don’t need to add fabric softener. Just a colour safe, mild detergent will do the trick - and definitely no bleach please; the girls are a little delicate and told us it stings their gussets.

Tip 4: Leave ‘em hanging!
They love to feel the wind in their hair so no fancy dryer necessary for them, a simple line dry in the shade will do the trick.

Tip 5: Do not tumble dry or dry clean.
We’ve never met anyone (that we know of) who takes their knickers to the dry cleaners. But just in case you love your undies so much that you think they deserve an upgrade from a regular wash, we’re here to tell you there’s no need. In fact, they don’t like the dry cleaners at all so best to keep them home (or wherever you do your regular wash) and clean as per Tip 3. They also don’t like tumble dryers so stick to a line dry as per Tip 4.

Tip 6: Do not iron.
There’s many reasons why it's weird to iron your undies. Prolonging the life of them is just another to add to the list.

Tip 7: Keep me trimmed.
Whatever your grooming style inside your pants, we recommend giving any rogue threads that appear on your undies a quick trim to keep them tidy and avoid threads catching.
nat’v isn’t one of your average apparel brands trying desperately to tick a sustainability box. Each and every piece we design and bring to the market must align with our core values of creating sustainable garments and giving more choices for like-minded women.

We’re not about doing stuff just for the sake of it; ain’t nobody got time for that. When creating pieces, there are two things that need to be ticked off before anything goes ahead:

Is this better for the end user in terms of comfort and cut? Is this better for our planet in terms of manufacturing processes, materials used, carbon and water footprint? If we get two yeses - that’s when we go into detailed design.

What we’re striving for with everything we create is the ultimate balance of comfort, sustainability and price point, to suit all women. So, no pressure then!

Really comfy

These are so comfy. Amazing highwasited waist band. Panties don't ride up your bum. I love that there are options from **** shades. I wear the beech as the "default ****" is always too light for my skin. These are great every day panties. They're not seamless around the leg opening so wouldn't recommend under legging or other tight clothing. I'm a size 6 and bought the 6-8 size.

C-section pouch

I have been searching for underwear that will flatten the pouch above my c-section scar, because normal/thin waistband undies make it look so much worse. These provide compression in exactly the right place. Perfect. I will be purchasing more.

Nice undies

I received the wrong size and did not realise until after I had worn them which is a shame, but apart from them being massively oversized they are really great quality!

How to care and prolong the life of your nat'v basics
nat'v basics are made from delicate natural fibres, so it's essential that you take care when washing them and caring for them. Read on!

7 tips to keep your knickers fresh
Washing your knickers may seem pretty straightforward, but how do you actually wash your knickers? Like most of us you probably, haven't put a lot of thought into it. And why on earth would you? You have a life—and that doesn’t include worrying about your knickers?
Personally I am the worst washer of any clothes and usually don’t think twice before doing the washing. Everything gets thrown in the same load on whatever setting, I am guessing the default one. So what’s wrong with that? Washing your Nat'v Basics with the rest of your laundry will ultimately cause them to wear out quickly which includes tears, fraying, fading, and stretching.

Here are some tips on how to care and prolong the life of your nat'v knickers.

Tip 1: Treat me delicately! Place your Cheeky Gs, Classics and pre-rinsed Comforts inside a delicates wash bag, with similar colours.
Pre-rinse your leak proof Comforts in cold water until the water runs clear.

Tip 2: Warm and gentle wash. Select a gentle cycle, not too hot, not too cold, just right.

Tip 3: Mild detergent, no harsh chemicals. Use a colour safe, mild detergent. Do not bleach or use fabric softener.

Tip 4: Leave me hanging! Hang me on the line to dry in the shade.

Tip 5: Do not tumble dry. Do not tumble dry or take me to the dry cleaners.

Tip 6: Do not iron. No ironing required here.

Tip 7: Keep me trimmed. If any loose threads appear, trim them to keep me tidy and avoid threads catching.
So it’s pretty straightforward!
By following our tips your nat'v basics are going to last a lot longer, which is great for your back pocket and our planet.
Do you have a size guide?
Please not we recommend sizing up in our bralette for extra comfort. For more information visit our size chart page

We aim to offer comfort to our customers by maintaining an open and honest supply chain, by checking and ensuring the highest quality working conditions exist at all levels, and by investing time and resources into researching the best techniques for material manufacture that have the least impact on the natural world.
