First Layers (Ages 0-8)

Long johns for toddlers and infants are one of the most important elements for children that ski, snowboard or just love having fun in the snow. Long johns, allegedly named after an old-time boxer, are a critical factor in keeping toddlers, teens, infants and juniors warm and dry when enjoying the often harsh outdoor snow and cold.

Kids’ Long Johns for Winter Warmth

Kids’ long johns should be a moisture-wicking layer to keep the skin dry. This lightweight wicking layer removes the sweat from the child's skin and holds the moisture on the fabric instead. This transfer prevents moisture from sitting on the skin, which then allows your child to remain warm and dry rather than becoming cold easily and quickly.

As previously mentioned, the second reason kids’ long johns are vital is for warmth. Long johns, especially fleece fabrics, are utilized for their insulation qualities, which traps the heat close to your baby’s body. On a cold, snowy winter day, thermal wear for infants, toddlers, and kids are just what they need to be protected and remain warm.
