The Sleep Store Merino Knitwear Onesie is a beautifully classic outer layer, crafted from 100% merino wool to keep babies cosy while still allowing them to move, wriggle, and explore. When you’re dressing your little one for cooler days, comfort and warmth are everything.

Made from soft merino knit in a stylish seed stitch, this onesie has a lovely textured finish that feels both timeless and special. The knit is warm yet breathable, helping regulate your baby’s temperature throughout the day. Merino is naturally insulating without being bulky, making it ideal as an outer layer over a bodysuit or singlet during autumn and winter.

Thoughtful design details make this piece as practical as it is beautiful. Wooden buttons run down the front for a classic look, while snaps along the legs allow the garment to be fully opened for easy nappy changes – especially helpful with wriggly babies. The round neckline and raglan sleeves provide extra freedom of movement, so your baby can stretch, crawl, and play comfortably.

Designed in classic, gender-neutral colours, this knitwear onesie is easy to mix and match with the rest of your baby’s wardrobe. For extra warmth on chilly days, you can even layer it with one of our cosy merino knit vests. Available in sizes from newborn through to 1 year, it’s a timeless piece that feels just as suitable for everyday wear as it does for special outings.
