SizeNB (50/56)
“The true secret of happiness lies in taking a genuine interest in all the details of daily life.”

Inspired by William Morris’s 1889 Mallow design, this beautiful print captures softly flowing stems and delicate cottage-garden blooms — a true celebration of Morris’s love for nature.

Part of a limited edition collaboration between Zipster and the William Morris Society, this exclusive Zipster was photographed inside the historic William Morris Gallery museum, bringing timeless British design to modern little dreamers. 🌿

Zipsters are a must have, providing comfort for your baby, and simplicity for you.

For the details:

• Zipsters are made from super soft and stretchy 95% bamboo and 5% elastane. It's gentle on your baby's skin and perfect all year round due its qualities. See why we love bamboo here.

Two way zip, perfectly concealed for safety and with a zip head engineered for parents with tiny or gigantic hands.

Fold-over hands up to 12M to avoid scratches during the night, and fold over footies on all sizes.

95% bamboo, 5% elastane

Limited Collection

Each piece in this collection was photographed inside the historic William Morris Gallery museum, connecting past and present in the very place where his legacy is preserved. With only a small number available, we don’t expect it to stay on the shelves for long. If you’ve fallen in love with a piece (or two!), now is the perfect time to make it part of your family’s story.

Questions parents ask

Will this help my baby sleep through night nappy changes?
Yes — the two-way zip opens from the bottom, so you can change a nappy without undressing your baby or fumbling poppers in the dark. Their chest and arms stay covered, so they're far more likely to stay asleep.
Can the zip touch or hurt my baby's skin?
No — and this is the part parents new to zips worry about most. A big, soft zip garage sits at the neck, and a full fabric guard runs behind the zip the entire length, from neck to ankle, so the zip is never against your baby's skin.
Is it good for babies with eczema or sensitive skin?
Yes — soft, breathable, OEKO-TEX-certified bamboo that's naturally moisture-wicking, helping keep sensitive, eczema-prone skin dry and comfortable. The smooth fibres and fold-over mitts minimise friction against delicate skin.
Does it have built-in scratch mitts and feet?
Yes — fold-over cuffs at the hands double as scratch mitts (up to 12 months), and enclosed fold-over feet in every size keep toes warm with no socks to lose. Fold-over feet in all sizes is unusual — many brands stop at 9–12 months.
I've never used a zip sleepsuit — why choose it over poppers?
Poppers mean lining up tiny studs one-handed at 3am; a two-way zip is one smooth pull, with an extra-large tab that's easy to find and grip in the dark. It turns a 20-minute wake-up into a two-minute one.
What room temperature is the babygrow for?
It's a lightweight, single-layer bamboo sleepsuit that regulates temperature well — ideal worn alone in a room around 18–22°C, or as a breathable base layer under a sleeping bag in cooler rooms.
What size should I choose?
It runs true to size — go by your baby's age, and if you're between sizes, size down. It's cut generously, so it fits 2–3 months longer than most sleepsuits.
How do I wash and care for it?
To keep it fresh as day one, we recommend washing on cold and line drying — it's the gentlest way to protect the fabric so it looks and feels like new, wear after wear.
Is this a good newborn or baby-shower gift?
It's the gift new parents actually use — the zip makes 3am changes painless and the bamboo is soft on newborn skin. Choose 0–3m or 3–6m, since newborn size is outgrown fast.
What makes a ZIPSTER babygrow different from other zip sleepsuits?
The covered zip that never touches skin (a full-length guard plus a soft neck garage), fold-over feet in every size, a generous cut that fits 2–3 months longer, OEKO-TEX-certified bamboo, and 200+ designs including officially licensed characters — designed in Amsterdam.
