Details
Made from 100% New Zealand Merino Wool rib knit fabric, this bodysuit feels wonderfully soft and snuggly against delicate skin. The rib construction gives it excellent stretch, allowing the fabric to gently “hug” your baby for a snug, comfortable fit that still allows freedom of movement. This stretch also makes it easier to get on and off wriggly little bodies, and it’s a favourite for cloth nappy users thanks to the flexible, accommodating fit.
Part of The Sleep Store’s Deluxe Merino Sleepwear range, this bodysuit is ideal for layering. Use it under a zipsuit or onesie with a swaddle or sleeping bag for night-time sleep, or pair it with a singletsuit, jumper, and leggings for a cosy daytime outfit. It has an envelope neckline and 3 press studs at the crotch making changes a breeze. Available sizing from newborn to size 2, in a range of soft colours.
At The Sleep Store, we’re passionate about helping children sleep better, and merino plays a big role in that. Often called the “miracle fibre”, merino is naturally temperature regulating, moisture wicking, odour resistant, and even naturally fire retardant. It helps children stay warm in winter, cool in warmer conditions, and comfortable without waking up clammy – all with the added bonus of needing less frequent washing.
The Sleep Store Deluxe Merino range is designed to deliver superior warmth, comfort, and durability for growing babies, toddlers, and children. Made from luscious 220gsm, 100% merino rib fabric, this range is thicker, warmer, and more hard-wearing than many alternatives on the market. Naturally temperature regulating and breathable, Deluxe Merino helps keep little bodies cosy in winter without overheating as they move and play. Soft, stretchy, and made to last, it’s the perfect layering range for better sleep and everyday warmth.

As with many wool garments, you may experience a bit of pilling on this garment. Please note this is often due to a soft fibre such as merino rubbing against other fabrics, such as flannelette sheets. We consider pilling a normal part of wear and tear on a soft merino garment. We could have treated the fabric much more to reduce pilling but then it would lose its lovely, snuggly softness.
Please take care with moths
Protect
your Merino from small holes created by insects such as moths and
silverfish. Ensure your garments are clean before storing. Lavender and
Cedar wood are noxious to these pests so storing your garments with
these scents or a moth trap will help protect your knitwear further.
Love your Merino and it will love you back!
What are the major differences between The Sleep Store Merino garments?
This merino wool and tencel blend is silky smooth against the skin has a comfortable stretch and is super lightweight. The tencel component makes this garment quick drying. Perfect for all year round use, it is the lightest of our merino blend offering at 165gsm. Amazing weight for warmer weather.
Jersey Merino
The jersey merino wool is super smooth and soft, feels like high quality t-shirt fabric and has a comfortable stretch to it - not as much as the deluxe merino wool rib. Great for all year round at 200gsm. Good for summer babies.
Deluxe Merino Rib
This is a rib knit merino wool meaning it's structure is made up of rows of stitching. This gives this merino a really beautiful stretch with cross grain elasticity. It is so soft and great for all year round at 220gsm.
Merino Tencel Fleece
The most fluffy fleecy softness on the inside, with a smooth sweatshirt look on the outside, and most definitely the warmest of them all at 270gsm.
