layering guide

Layering for Every Climate–How Many Layers Does Your Little One Need?

A simple rule is to dress your kiddo in one more layer than you’re wearing. For winter, this usually means 3-4 layers. Layering lets you adjust for temperature changes or activity levels—remove a layer during play to prevent sweat buildup and add it back when they cool down. Remember: dry layers mean warmer kids!

Layer Up with Jan & Jul:

  • Base Layers: Moisture-wicking and insulating for cozy warmth.
  • Fleece: Soft, breathable mid-layers for extra insulation.
  • Rain Gear: Waterproof protection for wet weather.
  • Snow Wear: Heavy-duty warmth for freezing temperatures.

Jan & Jul’s layering system keeps your child comfy and dry year-round, no matter the weather!

Note: Warmth varies with wind chill, sun exposure, and activity. These ratings are general guidelines.

I don’t usually leave reviews, but these have served us! My sone wears them day and night and they hold up so well and are so soft. He doesn’t want to take them off. I am hoping to buy these every year and that Jan and Jul keep them around. Don’t hesitate, buy these.

My 5 year old daughter loves to wear these fleece top under her clothes for school and it kept her dry when she played in the snow too! I highly recommend these fleece top to all my friends. The fabric is super soft and feels smooth on the skin! Gotta get the fleece pants too!

‏My kids usually never liked to wear base layers up until I found this brand. I initially ordered the pants to use it for skiing! Then, I ordered the tops as well because my kids literally loved it! They said the fabric keeps ‏them warm and doesn’t annoy them. For many years, it’s first time that they start wearing base layers even when we don’t go skiing. I highly recommend this product!

I am a fan of Jan and Jul’s clothes. They are soft and super comfortable! I bought one set last year for my daughter and she loves it so much! This year I bought one set for my older kid and he loves it too. Always love their products and the price is affordable. Highly recommended!
