Merino wool is known for its skin-loving qualities - it keeps baby warm when it's cold, and cool when it's hot. It's lightweight, durable, machine washable, and 100% natural, making it gentle on our planet. Breathable and soft on the skin (not itchy to wear), studies have shown that sleeping babies in merino tend to have a deeper, more restful sleep. 

Caring for Mello Merino garments is easy peasy! Being made with breathable fabric means airing a Mello garment for a few hours is usually enough to refresh and renew from 'kid' odours! When it does need to be cleaned, it is completely machine washable. 

Wash on a normal warm or cool wash cycle with wool detergent. Separate into lights and darks. As this is a natural fabric, please don't use softener or bleach.

Hang on the line in the shade to dry, so as to avoid fading, or pop in the tumble dryer in the medium heat (the fabric quite likes that!).

Please do not dry clean.

A warm iron can be used. If the fabric is printed, please don't iron prints or labels.

Always clean before storing - this helps to avoid "kid" odours. For best results, store folded rather than hung.

The durability of the fabric means it will keep its shape for years. Merino wool dries super-fast, making it perfect for busy families. It's also static resistant, so it picks up less dust, making it an excellent option for little ones with asthma or allergies.

Elisa and Juliet together have created Mello Merino built on the values instilled from their childhood. Using insights gained through overseas travel and their various adventures in life, they have drawn together skills each of us has acquired throughout the weaves of our careers.

Elisa was always outside as a child, looking for adventure wherever she would go. She would wear clothes that were not typical for girls; comfort and freedom to move were far more important. With a background in child psychology and working for not-for-profits, she understands how valuable it is for kids to feel free to play, explore, and move without restrictions.

Juliet (the creative one) has a strong sense of aesthetics. She has a background in fashion design and product development, which has led her to work with and develop a love of merino fibre. She is a traveler at heart and was sold on merino when starting her travels more than 20 years ago, replacing a bulky lamb’s wool jumper in her backpack for a lightweight merino top.

Together they design and create beautiful merino wool clothing which is made from the finest merino wool. Mello Merino clothing is designed with three key elements in mind: aesthetics, comfort, and durability for kids. They believe that timeless design and quality will allow for their pieces to be handed down to siblings, cousins, and friends, from one generation to the next.

Elisa and Juliet have created Mello Merino because they want kids to feel comfortable, confident, and have freedom of movement. It's all about kids feeling great wearing Mello Merino! The clothing embodies freedom and adventure, quality, and style. It’s about buying less and choosing well.
