The Children's PJ Set Set Viva con Agua supports something bigger: a water-themed print of waves, hearts and globes in blues, made with the Viva con Agua initiative for clean drinking water.

A long-sleeved top with matching pants in our signature stretchy bamboo, cut with a little added length so the set grows with them. Made for playing, sleeping and lazy days.

Made from 95% bamboo and 5% elastane: naturally breathable, temperature-regulating and OEKO-TEX certified, gentle on delicate, eczema-prone skin.

Sleep well, do good, and match the baby Viva con Agua Zipster. 2 to 8 years.

Questions parents ask

What is the Zipster x Viva con Agua collection?
Feel-good bamboo with a bigger purpose — our Viva con Agua x Zipster collection pairs beautifully soft babygrows and gifts with support for clean-water projects around the world. Three pieces, one powerful mission.
How does the Viva con Agua collection do good?
A meaningful gift for conscious families: everyday comfort plus the chance to do a little good. And bamboo itself is a gentler choice — a fast-growing plant that typically needs far less water to grow than conventional cotton.
Will these bamboo pyjamas keep my child comfortable all night?
Yes — bamboo is naturally breathable and temperature-regulating, so it helps stop your child overheating or getting too cold. Soft and gentle on the skin, it's made for a calm, comfortable night's sleep.
Are they suitable for children 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 are gentle against delicate skin.
Do they come in matching sizes for the whole family?
Yes — many prints come in matching baby, children's and adult styles, so the whole family can wear the same design. Children's sizes go up to 8 years — perfect for “mini-me” photos.
What age and size should I choose?
Our children's pyjamas run true to size — go by your child's age, and if you're between sizes, size up so there's room to move and grow. Available up to 8 years.
What are they made from?
Soft, breathable bamboo that's gentle on the skin and helps regulate temperature for better sleep. It's OEKO-TEX certified — independently tested for harmful substances.
Is this a good gift?
Yes — a matching family pyjama set makes a memorable, practical gift that gets worn again and again, and the bamboo is soft enough for the most sensitive skin. Lovely for birthdays, Christmas and new siblings.
How do I wash and care for them?
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.
What's included in the set?
A coordinated two-piece pyjama set — a top and bottoms in soft bamboo, cut for a relaxed, comfortable fit at bedtime.
