When the winter arrives, and it’s freezing outside, it can be tempting to keep your little one inside and safe from the cold. Norwegians, however, have been keeping their babies warm in harsh winters for hundreds of years. How? By clothing them with wool.

Our base layer set is made from 100% super-soft merino wool. When humans discovered this ‘miracle fiber', they began to use it to make clothing that keeps people warm, even in freezing cold climates. Merino wool is perfect for babies because the fabric keeps their fragile bodies warm and toasty while still regulating the body temperature. The result? A happy baby that isn’t too hot or too cold, but just right.

Our base layer set is made from the softest merino wool we’ve ever felt - it’s like butter! Therefore, it’s the perfect material to rest against your baby’s delicate skin all day long. Unlike normal wool, merino wool is made from super-fine fibers that are non-itchy. It's like it's made for babies' sensitive skin.

Merino wool stays warm when damp, so if your baby gets wet, they’ll still be comfortable. This "magical" fabric can absorb up to 30% of its own weight in moisture before it feels wet. It's also naturally antimicrobial and odor-resistant, so you won’t have to wash our base layers set as often as others.
When it’s extra chilly, be sure to wear the base layers next to the skin (the wool cooperates with the skin and it's important that there is no other fabric between the merino and the skin (except a diaper, of course).

Taking care of the base layers needn’t be any trouble as merino wool is naturally odor-resistant, anti-microbial, and grease-resistant. Simply put them in your washing machine on wool/delicate program with a good wool detergent, and let them air-dry afterward.
