A perfect option for babies born in Winter if you don't want to worry about too much layering, or if you live in a colder climate or house. 

This Merino Interlock is ultra-soft and ultra-warm at 210/230gsm. Merino Interlock has been woven with pockets of air to give it extra warmth and durability without the weight.

Why should you use merino against the skin for layering:

Merino should be used for all newborn babies 365 days of the year for night-time sleeping.  In fact on those warmer nights, it works BETTER than cotton to help regulate temperature and keep your newborn baby cool.  Newborn babies can not regulate temperature for around 12 weeks of life - this means they might be cold even when it's hot in the house.  So it is really important to use merino against the skin so the merino garment can do the job for them.

Merino will draw the moisture away from your newborn delicate skin when warm and then as the temperature drops (between 3-5am) the merino will push the warmth back into the skin - so they don't wake up because they are cold. If merino hadn't been invented by nature, you'd be forgiven for thinking it was invented by magic.
