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 Boys’ & Girls’ DOTKNIT™ Thermal Set is a warm, moisture-managing base layer designed for older kids and teens who stay active when temperatures drop. The two-piece set pairs a long-sleeve thermal top with coordinating bottoms, creating an easy first layer for skiing, snowboarding, outdoor school, winter hikes, snow days, 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. A slim fit makes the set easy to layer beneath fleece, snow pants, bibs, insulated jackets, and other winter outerwear without adding unnecessary bulk.

Built for Real Outdoor Use
Older kids and teens can work up plenty of heat even when the temperature outside says otherwise. The DOTKNIT™ Thermal Set gives them a dedicated first layer designed to combine warmth with moisture management during active winter days.
Start with it underneath snow pants and an insulated jacket for skiing or snowboarding, layer it beneath fleece and outerwear for outdoor school and winter programs, or make it the foundation for sledding, hiking, camping, and long days exploring outside. The slim-fitting construction keeps layering simple while giving kids room to build a cold-weather system around the conditions and activity ahead.
It’s an easy winter staple for the years when kids are carrying more of their own gear, managing their own layers, and heading toward bigger outdoor adventures.

Why ODSS Recommends It
The right first layer can make a big difference on long winter days outside. We like the DOTKNIT™ Thermal Set because it combines warmth and moisture management in a slim layer that older kids and teens can easily work into their own winter routine.
It’s a versatile starting point whether they’re pulling on snow gear for outdoor school, heading to the mountain for a day of skiing or snowboarding, or packing for a winter hike or family adventure. As kids become more independent with their gear, having a dependable top-and-bottom base layer makes building the rest of their winter layering system that much simpler.

Ordering bulk with Outdoor School Shop was just as easy and seamless as I had hoped!
