Moisture-managing thermal base layer set designed to keep little kids warm and dry during cold outdoor play.
Find Your Size
European sizes are based on your child’s height in centimeters. Because kids of the same age can be different sizes, height is the best guide for fit.
Enter your child’s height in inches, and we’ll show the closest CM size range. This correlates to the first number in the size option. ie: 98 or 122. If CM sizing is not provided, simply choose the age provided.
💡 Tip: These are general guidelines. Always check specific brand size charts when possible, as sizing can vary between manufacturers.
Product Description
The North Face Kids’ DOTKNIT™ Thermal Set is a warm, moisture-managing base layer made for little explorers who keep moving when temperatures drop. The two-piece thermal set pairs a long-sleeve top with coordinating bottoms, creating an easy first layer for snow days, outdoor school, winter hikes, skiing, sledding, and everyday cold-weather adventures.
DOTKNIT™ double-knit fabric uses targeted yarn construction for moisture management, while FlashDry-Pro™ materials actively pull moisture away from the body to help kids feel dry and comfortable during activity. The slim fit makes the set well suited for layering beneath fleece, snow pants, bibs, insulated jackets, and other cold-weather gear.

Built for Real Outdoor Use
A good winter layering system starts next to the skin. The Kids’ DOTKNIT™ Thermal Set gives active little explorers a dedicated thermal base layer for the cold days when staying comfortable means managing both warmth and moisture.
Wear it underneath snow bibs and an insulated jacket for snowy adventures, layer it under fleece and outerwear for outdoor school, or make it the starting point for winter hikes, sledding, skiing, and long afternoons playing outside. The slim-fitting design keeps layering simple without adding unnecessary bulk beneath other cold-weather gear.
It’s made for the kind of winter childhood we love at ODSS—snow-covered boots by the door, rosy-cheeked afternoons outside, sledding hills, winter trails, and kids who would rather keep exploring than head inside.
Things to Know

- Slim fit: This set is intentionally designed with a slim fit that works well as a first layer underneath additional clothing.
- Moisture management: DOTKNIT™ and FlashDry-Pro™ technologies are designed to manage moisture during activity.
- Not outerwear: This is a thermal layering set rather than a waterproof, windproof, or insulated outer shell.

Why ODSS Recommends It
Cold-weather adventures are a lot easier when kids start with the right layers. We love the DOTKNIT™ Thermal Set because it gives little explorers a warm, moisture-managing first layer without adding unnecessary bulk underneath their winter gear.
It’s the kind of set that can become part of the everyday winter routine—pull it on before snow bibs for outdoor school, layer it up for a family hike, or start here before a long afternoon of sledding and snow play. With a comfortable slim fit and moisture-managing fabric made for movement, it helps kids stay comfortable while they get busy doing what winter childhood is all about: getting outside and exploring.

For us, the right gear from ODSS supports what we believe most about childhood. When children are able to be outside every day, in all seasons, they become tenacious, confident, and develop an authentic relationship with the land.

Ordering bulk with Outdoor School Shop was just as easy and seamless as I had hoped! As we open up a new program, preparing our first group of kiddos for any weather was at the top of our priority list, and ODSS came through with insight, expertise, and the coolest, most dependable gear around! Thank you ODSS!
