Child wool clothes can be a great way to keep your kids comfortable and cozy on cold days. The fabric wicks away moisture and regulates temperature, so it’s perfect for staying warm in the winter and cool in the summer.

Merino wool – The natural fibers of wool absorb large amounts of moisture, which makes it one of the most breathable fabrics on earth. When it’s hot out, the vapor in the wool evaporates and moves it away from the skin, keeping your child cool; when it’s cold out, the vapor condenses and puts off heat.

They’re naturally odor-resistant and antimicrobial, too. The lanolin in the wool repels bacteria that causes bad odors, so they don’t need to be washed as often.

Chasing Windmills Long Johns – This brand’s merino wool long johns are designed to make it easier for kids to spend more time outdoors. Their designs evoke the playful, adventurous spirit of childhood. They also offer long johns in size 3-6 months and a coordinating short john for little ones.

Ella’s Wool – Ella’s Wool is a small New York City company that produces high-quality, incredibly soft merino wool layers for babies and children. Their long-sleeve and tank tops come in marled grey, light blue, and light pink. They also have thicker wool leggings called Tubes that are a great option for a stand-alone layer in the cold. They also sell merino footed pants and wool onesie pajamas for complete sets.

Nui Organics – This New Zealand company naked has a wide selection of beautiful, functional products for kids. Their merino wool baby blankets are super soft but durable enough to last through the years, making them a great choice for building your child’s capsule wardrobe.

Simply Merino – All of the merino wool base layers that this company offers carry the Responsible Wool Standard and OEKO-TEX Standard, which means that they are made from ethically and sustainably produced materials and can be certified to be free from harmful chemicals. They also take special care to lessen their impact on the environment, like using biodegradable labels and using compostable mailers.

Iksplor – Their merino wool hoodies, tees, and leggings are a good option for growing kids. They’re made of a blend of merino and a synthetic fiber, but they feel soft and comfortable as if they’re a 100% wool product. They also carry a merino sleep sack that’s so versatile, we’ve taken it backpacking!

They sell a lot of items that are a great value for the money. They have a wool base layer set (long-sleeve shirt and pants) that sells for $84.

These long johns are great as a base layer in the winter or for wearing as pajamas. They have double reinforced knees, which I love when my baby is crawling. They are available in ecru with a whimsical windmill design and are sized from newborn to 3t.

The company also sells a variety of wool tops and bottoms for kids and adults. Their merino wool tops are great for wearing as a layer under other clothing, too.
