When it comes to outdoor activities in the winter, keeping your little ones warm and cozy is a top priority. That’s why investing in quality kids base layers is essential for any cold-weather fun. Not only do they provide an extra layer of warmth, but they also help to regulate body temperature and wick away moisture.

But with so many options available, how do you know which ones are the best for your child? Don’t worry, we’ve got you covered.

Toddler Snowsuits

For young children, a toddler snowsuit is an excellent option for a base layer. These one-piece suits are designed to keep little ones warm and dry in the harsh winter weather. They come with insulated layers, waterproof outer shells, and even built-in mittens and booties.

Plus, they are easy to put on and take off, making them perfect for busy parents on the go. Some top-rated brands for toddler snowsuits include The North Face, Columbia, and Patagonia.

Thermal Underwear

For older kids, thermal underwear is a classic choice for a base layer. Made from materials like merino wool or synthetic fabric, these undergarments provide both warmth and breathability.

They come in various styles, including long-sleeve shirts, leggings, and even full-body suits. Some brands that offer top-rated thermal underwear for kids are Icebreaker, Smartwool, and Under Armour.

Wool Base Layers

If you’re looking for a natural and eco-friendly option, wool base layers are worth considering. Merino wool is an excellent choice for kids as it is soft, lightweight, and naturally antimicrobial. It also has excellent moisture-wicking properties, making it ideal for active children.

Wool base layers come in various thicknesses, so you can choose the right one based on the temperature and activity level. Some popular brands for wool base layers are Woolly, Helly Hansen, and Minus33.

Fleece Base Layers

For those particularly chilly days or high-altitude adventures, fleece base layers can be an excellent choice. Offering superior warmth and insulation, these layers are often lightweight and very breathable. Best of all, the material is extremely soft to the touch, making it comfortable for children to wear for extended periods.

Fleece base layers are available in a variety of styles, including tops, bottoms, and all-in-one suits, catering to different needs and preferences. Noteworthy brands providing high-quality fleece base layers for kids include Polartec, REI Co-op, and Columbia.

Synthetic Base Layers

When it comes to versatility and performance, synthetic base layers are a wise choice. These base layers are typically made from polyester or polypropylene, providing excellent moisture-wicking capabilities and quick-drying properties.

They are lightweight, durable, and often less expensive than wool or silk options, making them a popular choice for active kids. Additionally, synthetic materials tend to retain their insulating properties even when wet, which is a bonus for any snow play or winter sports. Brands like Patagonia, Under Armour, and Columbia have a range of synthetic base layers that are well-reviewed and highly recommended for kids.

Tips for Choosing the Right Kids Base Layers

When shopping for kids base layers, there are a few things to keep in mind to ensure you get the best ones for your child. Here are a few things to keep in mind:


As mentioned, there are various materials used for base layers, each with its own set of benefits. When choosing the right one for your child, consider the temperature and activity level they will be in.

For colder temperatures and high-intensity activities, merino wool or synthetic fabric would be the best choice. For milder temperatures and lower-intensity activities, cotton or blends may suffice.


It’s essential to find base layers that fit your child snugly without being too tight or restrictive. If they are too loose, they won’t provide enough warmth, and if they are too tight, they may cause discomfort and restrict movement. Many brands offer size guides to help you choose the right fit for your child.


Base layers are meant to be worn under other clothing, so it’s essential to consider how they will fit with your child’s outer layers. Avoid anything too bulky, as it can make layering difficult and uncomfortable for your child.


Kids grow quickly, so it may be wise to invest in base layers that have room for growth. This way, your child can continue to wear them for a few seasons before needing to size up.

Care and Maintenance

It’s essential to consider the care and maintenance of the base layers. Kids can get messy, so you’ll want to choose base layers that are machine-washable and durable enough to withstand frequent washing. Check the care label on the garment before purchasing base layers, especially those made from wool, which may require special care to maintain their quality and function.

Additional Tips for Staying Warm

Besides investing in quality kids base layers, there are a few other things you can do to keep your little ones warm during cold weather activities. Here are a few additional tips:

Layer Up

Aside from base layers, make sure your child has at least one other layer of clothing, such as a fleece or sweater. This will provide extra insulation and keep them warm.

Cover Exposed Areas

Don’t forget to cover the extremities, such as the head, hands, and feet. A hat, gloves or mittens, and thick socks are necessary for keeping these areas warm and protected from the cold.

Take Breaks

If your child starts to feel too cold, take a break indoors to warm up. This will prevent them from getting too chilly and ensure they can continue to enjoy their outdoor activities.
