Best Kids’ Thermals & Long Johns Rated in 2018

Whether you live in a cold climate or not, chances are at some point during the year, your child will need some thermals or long johns to keep them warm. These can be worn indoors as comfortable pajamas or outside, alone or layered for the best cold protection. Layering clothes for outdoors is a well-recognized practice, especially in the northern areas. Warm air is trapped in-between each layer, so your body is insulated better than with just a single layer of clothing. Three separate layers are ideal/ these should be a base layer against your skin, a middle layer, and then an outer layer. Sweat is drawn away from the skin with these varied layers in a process called wicking.

Each layer serves a purpose in protecting the body. The first wicks the sweat away, the middle one holds in body heat, and the third protects you from the weather elements. We highlight thermals and long johns for both boys and girls with all child age ranges represented. You should be able to find several choices for your child in this list. We feature only the items that parents and buyers are raving about and would certainly purchase again in the future. Here is our list of the best-rated and mostly-bought thermals and long johns for kids in 2018.

FAQs

Frequently Asked Questions
Q: Size is the biggest concern for clothes for kids. What size should a parent buy for their child? One that is the regular clothes size, one bigger, or one smaller?

A: When purchasing these thermal and long john sets, buy the size that is the same size as the child’s regular clothes for the best fit. If you are concerned about it being too small, then get a size larger, so the child has moving room. Also consider that the child is still growing, so a larger size will give them longer to wear the set.

Q: Can a girl wear the boys’ sets and a boy wear the girls’ sets? Some of the colors are not offered in the other sets.

A: Yes, girls can wear items for boys, but be careful about the sizes. Boys’ sizes tend to run larger than girls’ sizes. Also, the crotch pocket may be an issue for some girls, but this will be up to the parents who do the ordering for them.

Q: Are all of these full-length? Are there any that are short-sleeved or half-calf?

A: Yes, all the sets are full-length. None of them have short sleeves or half lengths on the legs. These are for cold weather, so full coverage is desired for this. The sleeves and legs can be rolled up or folded to get the look you want.

Q: What is the best advice for washing these thermals and long johns? Do they need special washing or drying care?

A: Most of the sets can be washed and dried in the machine. No special instructions are necessary, as these are comfort clothes that need minimal care. They will not even hold a crease if they are folded, so they are great for traveling.

Q: Can you order a different color top than the bottom or do they have to be the same color?

A: No, none of these sets come in different colors for tops and bottoms. You can make the set you want by purchasing more than one set and mixing them up as you like.

Q: Which ones would be the softest to wear, especially for sensitive skin?

A: The softest thermals and long johns are the ones that are fleece-lined and made mostly of polyester. The ones made of mostly cotton are soft to wear too, but the polyester is a bit softer to the skin. For sensitive skin, choose the ones that are not made with harmful dyes, such as the City Threads Long Johns. Makers will let you know if their products are specially made for kids with skin issues.

Q: Would these be too bulky to wear under regular clothes and under a jacket or coat?

A: No, these would not be bulky to wear for layering clothes. They are designed for that. The material is thin yet warm enough to allow for several layers underneath and on top.

Q: Kids will wear these for outdoor winter sports, so will they withstand that kind of wear and activity without tearing and ripping apart?

A: Yes, these sets are built for durability and much use by kids. They will last a long time, even under the most adverse conditions.
