  • Temperature & Layering

    Merino is unlike any other fabric, natural or synthetic. This special wool is a powerful natural thermo-regulator for the body, warming and holding heat in when the ambient conditions in the room are cold, then doing the exact reverse to cool the body down if excess heat is present. For layering underneath, please choose natural breathable fibres - Merino PJs are well worth considering, especially if your nursery dips below 18°C regularly. 

    Choose from two different weights to best fit your environment

  • ALL SEASON (0.7 - 2.4 Tog equivalent). Versatile and great value, this weight features 2 layers (240gsm Superfine Merino lining and GOTS Organic Cotton outer) - Best for use in nursery temperatures ranging from 17 to 27°C.
  • WINTER WEIGHT (2.5 - 3.5 Tog equivalent). Extra cosy for colder climates - these the highest merino content available on the market. Featuring 4 layers (440GSM Merino lining, Bamboo inner and GOTS Organic Cotton Outer) - Best for use in nursery temperatures ranging from 12 to 21°C

    Merino & Sleep

    What does it mean when we say that Merino improves sleep quality?

    It sounds a bold claim but it really is true. Merino wool has a hidden magic that makes it different to any other fibre on earth. Superfine Merino has a superior ability to breathe and naturally regulates both moisture and temperature, trapping thousands of tiny air bubbles in and creating a cosy micro-climate around your little one and to keep them comfortable and feeling 'just right' all night.

    The ability to detect when heat is building up 'too much' is unique to Superfine Merino. When temperature changes in the environment occur a subtle but very powerful natural process occurs within the fibres of the wool (the wool geeks will want to know that this is called 'heat of sorption and/or desorption depending on which way the heat is flowing'). Heat is actively conserved or released depending on the conditions (mother nature we love you).

    It is thanks to these incredible natural attributes that studies show sleep patterns improve when sleeping in Merino. Babies who sleep in merino have been found to settle more quickly, sleep more deeply, spending longer in the deep restorative phase of sleep where growth and development occurs and overall spent longer asleep.
