Product Description

Details

The Premium All Seasons Cotton & Merino Sleeping Suit has been thoughtfully designed to take the guesswork out of dressing your baby or toddler for sleep, offering comfort and peace of mind all year round. Designed to be used in room temperatures of approximately 18 to 25°C.

Crafted from two layers of natural fibres, the outer layer is 200gm organic cotton, and the inner layer is a 200gm merino lining. This suit combines the softness and breathability of cotton with the temperature-regulating magic of merino wool. Cotton feels gentle against delicate skin, while merino naturally keeps your child snug in the cold and cool in the heat. The result is a cosy, breathable sleep suit that adapts beautifully to changing conditions, helping your child sleep soundly no matter the season. 

Unlike traditional sleeping bags, this premium design features legs, making it ideal for active toddlers who like to move or for children who may be transitioning to a big bed. The grippy fold-over feet keep little toes warm at night but can be left open for playtime or morning adventures, offering flexibility and practicality. The under arm snaps allow you to get a more cosy fit when between sizes, so the suit stays secure and comfortable as your child sleeps.

Parents will also appreciate the high-quality zip closures, making late-night nappy changes or early morning wriggles that much simpler. Available in sizes 2, 3 and 4 years, this sleeping suit grows with your child through those busy toddler years. To make bedtime extra special, each suit comes in a range of stylish, in-house designed prints, created to look as beautiful as they feel.

Every detail has been considered to support better, safer sleep for your little one – and more peace of mind for you.

I'm naturally fluffy

These garments are naturally fluffy but washing separately for the first few washes will help the natural wool fibres on the inside to settle and will free any excess fluff.

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!
