The MookieMerino Difference

The MookieMerino 4-Season Sleep Bag’s two layers of 100% Extra Fine Australian merino wool, with a quality rating of 17.9 microns, is unique in the market and provides your baby with the full range of benefits that merino wool has to offer.

Not only are the vast majority of sleep bags made of lesser quality wool, with a rating of 19 or 20 microns, they only use a single layer of merino wool combined with a layer of an inferior material, therefore nullifying the majority of the benefits provided by merino wool.

The merino wool used in MookieMerino’s sleeping bags provides a temperature-controlled cocoon around a sleeping child, resulting in a deeper and more restful sleep for your baby. It is breathable and wicks moisture away, keeping your baby dry and warm. This is extremely important since it can take up to one year for newborns to be able to regulate their own body temperature. Merino wool truly provides peace of mind to parents, who can rest assured their little Mookies stay snug the whole night.

We do not chemically treat our garments with nasty chemicals in any way during or after the manufacturing process, keeping them pure and safe.
