The merino wool baby jumpsuit: a gentle cocoon for the early months
A baby jumpsuit knitted in merino wool forms a gentle envelope that covers the body from chest to legs. In the first days, when a newborn's temperature regulation is still immature, this enveloping piece provides a layer of gentle warmth while allowing your baby to move freely.
Each piece is knitted and made in Île-de-France by our French knitwear specialists. Assembly by linking: this operation consists of picking up each stitch of the knit one by one to achieve refined finishes. The wool is spun by French mill Fonty, founded in the 19th century in Creuse and awarded the Living Heritage Company label. When designs feature boxwood buttons, these are made in Jura by a manufacturer established since 1910.
The Charlotte baby jumpsuit or the Iris baby jumpsuit naturally find their place in your hospital bag. Their button fastening makes daily dressing easier and allows you to open the jumpsuit without excessive handling.
Wool baby trousers: freedom of movement and versatility
Merino wool baby trousers naturally follow your infant's movements while remaining gentle around the tummy and legs. Paired with a cardigan or jumper, they allow you to build versatile outfits and adjust layering according to indoor or outdoor temperature.
The Chachou baby trousers, like the Chacha, are crafted in fine merino wool—soft, breathable and naturally temperature-regulating. The supple knit accompanies first movements and motor discoveries without restricting your baby.
For newborn essentials, jumpsuit and trousers don't compete: they complement each other. The jumpsuit wraps baby in a single piece; trousers make layering easier and allow you to compose different outfits throughout the day.
Why choose merino wool for newborn essentials?
Fine, soft and supple, merino wool offers a pleasant feel against your baby's delicate skin. Naturally temperature-regulating, it helps preserve warmth when cool while allowing air to circulate when temperature rises. Breathable, it also absorbs moisture and helps reduce clamminess.
This ability to respond to temperature changes makes it particularly suited to first garments and layering throughout the seasons.
Superwash treatment allows machine washing at 30°C maximum, on wool or delicate programme, ideally in a mesh bag. Drying is done flat, away from heat sources and never in a tumble dryer. Well maintained, the knit preserves its softness and shape longer and can be worn by several children.
French craftsmanship, from yarn to knit
Every Mistricotine jumpsuit and pair of trousers is part of French manufacturing: wool is spun in Creuse by Fonty mill, then knitting and making up are carried out in Île-de-France. Pieces are produced in small batches with particular attention paid to knit quality and finishing.
This commitment has its roots in the house's story, born from Sophie's intimate experience of prematurity with her twin sister. It feeds the same intention: to create gentle, comfortable and elegant garments for newborns, inspired by the French tradition of the birth trousseau.
Pieces designed to be worn and passed on
A Piou-Piou playsuit, an Inès jumpsuit or Chacha trousers are designed to be truly worn every day. The quality of merino wool, the care brought to the knit and appropriate washing allow pieces to be kept as baby grows and, when well preserved, to be passed on to another child.
This transmission is part of the Mistricotine spirit: a garment accompanies the first months, gathers memories and can continue its story from one child to another.
Each piece is knitted with the same attention to detail that defines our entire range. The merino wool we use is known for its remarkable properties: its fibres are finer than those of traditional wool, which explains its softness. Its natural crimp creates tiny air pockets that regulate temperature, keeping your baby comfortable whether indoors or during an outing.
The jumpsuits and trousers we offer come in various colours to suit your preferences while remaining versatile. Neutral tones blend easily into any wardrobe; deeper shades add character to daily outfits. Each hue is carefully chosen to remain timeless and easy to coordinate with other pieces.
Shipping to Europe and internationally starts at €9.50. Gift box offered from €90. All orders placed before noon are dispatched the same day, except weekends and bank holidays.

Can you dress baby in a wool jumpsuit in summer?
Yes: merino wool is temperature-regulating. It retains warmth without causing overheating, allows skin to breathe and absorbs moisture. A lightweight merino jumpsuit suits cool summer evenings as well as winter days.
Are wool trousers suitable from birth?
Yes, provided the size matches your baby's build. Merino knit trousers don't compress the tummy and follow natural movements. Paired with a cardigan, they compose a versatile outfit for the first days.
What top should I pair with wool baby trousers?
A merino wool cardigan, jumper or vest pairs naturally with trousers. This combination allows you to adjust layers according to temperature and makes nappy changes easier than a full jumpsuit.
