Discover Your New Go-To Undies

Truth is, your undies work harder than most of your wardrobe. From school drop-offs and Zoom calls to sneaky sofa naps and supermarket dashes, they're with you through it all. What if your underwear could feel just as comfy as your favourite tee, while holding it all together underneath? Enter Janira Flexi-Adapt, our answer to stiff, scratchy, one-size-fits-none basics. These aren’t your average cotton undies. They’re breathable cotton-rich underwear with giggle-proof gussets, jersey cotton panties and seamless finishes, perfect for everyday wear.

Janira Flexi-Adapt: One Size That Actually Fits... most

Forget the stretch that snaps back like a rubber band. Janira's Flexi-Adapt fabric is where soft compression meets clever shaping. Built to adapt to your body’s unique curves, it hugs without squeezing. The magic is in the flexible stretch fabric that adjusts to a wide range of sizes with no digging, no bagging, and no awkward shifting. Unlike mass-market brands that offer rigid sizing and often ride up or lose shape, these feel custom every time. Plus, it's designed for women of all shapes, because Women's Underwear should work for every woman. Wondering if they run small or true to size? Thanks to Flexi-Adapt, they fit most beautifully up to a size 18.

Cotton-Rich Comfort That Breathes

We love luxe, but we live in cotton. That’s why our Janira Flexi-Adapt styles are made from organic cotton-rich blends that let your skin breathe while still offering a polished, secure fit. Whether it's ribbed cotton briefs, bikini briefs or a cotton jersey boy short, they feel like a soft hug rather than a straightjacket. These breathable cotton undies support your lifestyle while reducing your carbon footprint. They're made for lounging, layering under pyjama tops, or pairing with wireless bras for everyday ease.

Giggle-Proof Gussets: No Worries, Just Wear

Life’s too short for undies that don’t have your back (or your front). Janira's unique terry -cotton gussets give you a little giggle-protection. While these are not designed as leak protection underwear, they do offer a little absorbency vs a regular cotton-lined gusset brief. Briefs from the Janira collection give a little extra piece-of-mind. It’s underwear innovation without compromising comfort or softness. No awkward adjustments needed, just grab and go.

FAQs

1. Can I wear these undies all day?
   Yes! They’re designed for breathable comfort and flexible support, so you can wear them from AM to PM, even during long-haul flights.
2. Will these shapewear pieces roll down or dig in?
   Nope. Features like seamless finishes, flexi boning, and elasticated waists keep everything in place without discomfort. But every bottom and tummy is different so you need to shop for the best shape of underpants to suit your body.
3. Are these undies suitable for plus-size bodies?
   Not really. Janira offer some styles up to a 2XL or AU size 18 but we are continuously looking for styles that come in plus sizes to be more inclusive.
4. Do these styles show under tight clothes?
   Some styles with lace might show through clothes although many of the Janira shapewear or Janira briefs are designed to be invisible under clothes. 
5. Are they machine washable?
   Yes, just follow the care instructions. To extend their life and support sustainability, we recommend using a gentle cycle and a sustainable wash bag.
