Because innovation matters

Kids go through seven sizes in just two years making textile waste a serious issue in kidswear. Flexisuit™ addresses it at the source with a patented expanding-fit design that grows with a child across multiple sizes, so families buy fewer garments. 

GOTS-certified materials reduce the environmental burden of production. Together, these choices form a circular approach that lets parents make a lower-impact choice without compromising on quality.

  • Save money

    We estimate the average cost of a standard organic bodysuit or onesie is say $20. Over the course of two years baby will go through seven sizes (from 0000 - 2) $20 x 7 =$140.00 1 x Flexisuit = $39.95
    Save over $100

  • Reduce textile waste

    The world produces 92 million tonnes of textile waste every year. Baby and children's wear accelerates this cycle because babies outgrow clothes quickly, leading to millions of barely-worn items being discarded or stored unused.

  • Organic cotton

    Flexisuit™ is made with 96% certified organic cotton giving it a quality, soft hand feel. GOTS certifed organic means that the materials used are better for the environment, plus production processes and workers' welfare have been approved.

Don’t just take our word for it: real families share why they love Flexisuit™

 genuinely surprised

As a first-time mum, figuring out baby clothing sizes felt so overwhelming; especially during those awkward in-between stages when my little one seemed to outgrow everything overnight. I was genuinely surprised by how well it stretched while still keeping its shape. My baby was able to wear it comfortably across multiple sizes, long after other outfits no longer fit.

love that it will grow with the baby. Super soft. Will save money in the long run, as we will not be purchasing suits every few weeks.

- Donna, verified parent

Easy to get on and off as they’re so stretchy, colours are lovely too. Fabric is beautiful and soft and I love how easy they are to layer as they fit snugly.

We’ve been absolutely loving our Flexisuuit Onesies! The quality of the certified organic cotton feels so soft and gentle on bub’s skin, and the stretchy design means it grows beautifully with them from newborn size 0000 all the way up to 2 years old. We also love how practical and sustainable they are — less waste and more wear! Such a comfy, stylish everyday essential for little ones

96% certified organic cotton

Certified organic cotton is gentle on little ones, with fibres that are naturally soft and breathable and stay comfortable against delicate skin all day. Because it is grown and processed without harsh chemicals, it is a kinder choice for babies and children with sensitive skin, and it tends to get softer with every wash rather than wearing down. GOTS certification gives parents added peace of mind, confirming that the fabric is organic and that harmful substances are kept out of the finished product. The benefits reach beyond the wearer too, since organic farming uses less water and protects soil health and the farmers who grow it.

Quality, thoughtful design

Flexisuit is thoughtfully designed with quality at its core, built to handle the wear and tear of everyday play. Reinforced panels in high-impact areas add durability where little ones need it most, so the suit holds up through crawling, climbing and countless washes.
