Product Description

Details

The Sleep Store Deluxe Merino Singletsuit is a beautifully versatile layering essential for babies and toddlers, designed to keep little bodies warm, comfortable, and well regulated day and night. Perfect for use on its own in milder weather or as a base layer in cooler months, this singletsuit is one of those pieces you’ll reach for again and again.

Made from 100% New Zealand Merino Wool rib knit fabric, this singletsuit feels wonderfully soft and cosy against delicate skin. The rib construction gives it excellent stretch, allowing the fabric to gently hug your baby for a snug, comfortable fit while still allowing freedom of movement. It’s easy to pull on and off, making dressing and nappy changes simpler, even with wriggly little ones.

Part of The Sleep Store’s Deluxe Merino Sleepwear range, this singletsuit is ideal for layering. Use it under a zipsuit, onesie, swaddle, or sleeping bag for night-time sleep, or pair it with a jumper and leggings during the day for a cosy, breathable 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.


About the Deluxe Merino Range
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.

Care for your merino

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?

Basics Merino
At 190gsm it is the lightest weight of our 100% merino wool offerings. It is soft to the touch and offers a nice stretch. It is a great option during the warmer months worn on it's own, perfect base layer during the cooler months and our most affordable and durable option. 
All Seasons Merino Tencel
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.
