Designed for active explorers who love outdoor adventures even when temperatures drop, our limited edition Curiosity Gilet provides protection from the wind and rain without compromising on movement or comfort.
Growing with your LittleHuman from 1 to 5 years old, the gilet offers dual layer protection. Made from recycled plastic bottles, the outer layer is a patent pending ripstop fabric which is super durable and perfect for climbing, crawling and clambering, whilst the inner is a soft and insulating microfibre. It is of course machine washable, quick drying and contracts back to its smaller size time and again.
Having spent over 2 years in development, the Gilet is not only Petit Pli’s thickest garment but is the first of its kind in the world pushing the boundaries of material innovation and performance - a unique gilet for unique LittleHumans!

Yes. Safety is our baseline, not an afterthought.
All Petit Pli childrenswear complies with UK childrenswear regulations, including cord safety and chemical safety requirements. Our garments are tested to ensure they meet strict standards for products worn by babies and children.
Formaldehyde testing
All fabrics are tested for formaldehyde and other restricted substances in line with UK and EU regulations. Our materials are Oeko-Tex certified or tested to equivalent non-toxic standards, meaning they are verified safe for direct contact with skin.No PFAS or fluorocarbons in our DWR
For our water resistant outerwear, we use a fluorocarbon-free DWR finish. That means no PFAS, no PFCs and no “forever chemicals”. Our coating technology is certified free from fluorocarbons, so you get performance without unnecessary chemical risk.No chemicals used to create the folding mechanism
The expanding function of our garments is mechanical, not chemical. The pleats are engineered through structure and heat-setting techniques, not through coatings or chemical treatments that sit on the surface. Nothing is sprayed or added to make it “grow”. It is always built into the textile itself.We design with aerospace precision, but always for a child’s everyday life. Every stitch, fibre and finish is selected with safety, durability and responsible manufacture in mind.
If you ever have a specific question about materials or certifications, just ask.

We developed & patented a novel textile technology that grows bi-directionally to grow with LittleHumans.
Simply adjust the baby-safe velcro tab at the ankle whenever worn. The elasticated waist will only need adjustment every 3 months, as the child grows.
And yes, it shrinks back after every wear!
