*Microns denotes the quality of merino wool: the lower the number the better the quality. A 17.9 micron garment is deemed Extra Fine and is recommended for babies according to Woolmark which is a worldwide wool association. Extra Fine merino is a super premium wool used in the highest quality knits.



The award-winning MookieMerino wool sleeping bag has been meticulously designed, from concept to fabrication, with baby’s needs and safety in mind, without compromising on quality and excellent craftsmanship.

The MookieMerino 4-Season Sleep Bag is a proud recipient of the prestigious Woolmark Nurture certification which applies only to the finest Woolmark-certified materials. It is a symbol of quality assurance, proving fibre content and fitness for purpose through strict testing, which follows global industry standard, making it a coveted sleep bag.

The merino wool and trimmings are proudly certified by OEKO-TEX Standard 100 Class I for babies and this certification also means it is meeting the European REACH standards. The wool is from non mulesed sheep as certified by Deloitte and our factory has been audited by BSCI (Business Social Compliance Initiative).

Our baby sleeping bag is conforms to both UK BS 8510:2009 and AS/NZS 1249:2003 standards which are kids’ sleepwear safety regulation in the UK and Australia/New Zealand.

The MookieMerino 4-Season Sleep Bag is perfect for a room temperature between 16 and 20 degrees Celsius (61 and 68° degrees Fahrenheit) – the recommended room temperature by experts – and colder/warmer room. If the room is colder and the baby feels cold (by touching the baby on the back or chest), you can add a thin long sleeve top underneath the sleep bag.

Our merino is 200 GSM (Grams per Square Metre) jersey per layer – total of 400 GSM for a single merino baby sleeping bag since it has 2 layers – making it soft, light and comfortable to wear.

You can easily wash our wool baby sleeping bag in the washing machine, ideally inside out, at a gentle cycle (maximum 40 degrees Celsius / 104 degrees Fahrenheit) using a wool-approved detergent. Please do not bleach nor use fabric softener, do not tumble dry and dry away from the direct sunlight. There is no need to wash your sleep sack often, since merino wool is antibacterial meaning it is germ, dirt and odour resistant. Our merino wool baby sleeping bag dries quickly.

As for the size of our merino baby sleeping bag, the length is 89 cm (35 inches) and the width at the feet is 45 cm (18 inches).
