Organic Cotton Zip-Up Sleepsuit – Grey
Couldn't load pickup availability
Nappy changes at 3am just got easier. Our zip-up sleepsuit in Grey is made from sustainable organic cotton — ultra-soft on delicate skin, quick to change, and gentle enough for every wash. Because sleep matters for everyone.
Key Features
- Two-way zip: a concealed front zip that opens from the top or bottom, so night-time nappy changes are quick and less disruptive.
- Built-in scratch mitts: fold-over mitts on smaller sizes keep tiny hands warm and stop accidental scratches.
- Feet in or out: with feet up to 9 months and without feet over 9 months.
- Organic cotton: soft, breathable and grown without harsh chemicals, so it’s kind to sensitive skin.
- Sizes: 0–3, 3–6, 6–9 and 9–12 months.
A soft grey sleepsuit is a gender-neutral staple for day or night. Pair it with one of our organic cotton sleeping bags on cooler nights.
FAQs
Q. Which size should I choose?
A. Go by your baby’s age and size. If they are between sizes, choose the bigger one so they have room to grow.
Q. Does it have feet?
A. Sizes up to 9 months have feet. The 9–12 month size is footless.
Q. What can my baby wear it with at night?
A. Our sleepsuits fit comfortably under our organic cotton sleeping bags. Our tog guide shows what to layer for the temperature of the room.
