Should Thermals be Tight or Loose Under a Sports Uniform?

With school in session around the country, it also means the return of school sports. If your kids are active, whether it be football, baseball, or other team activities, boys’ thermals may be part of the sport's uniform. While all these activities will keep your kid warm, if not hot, you may not realize how essential boys long johns can be for winter sports. Even with all these benefits, you want to ensure the right fit so your kid can take advantage of them and not be left sweating out in the cold.

How Should Thermals Fit?

Thermals, or base layers as you may have heard them called, should have a snug fit. Kind of like a second skin. This helps maximize the effectiveness of the base layer. If they're loose, there will increase gaps between your kid's skin and the fabric, which will allow cold air to sneak in. It's best to go with your kid's actual size. Keep in mind that they are supposed to fit snug due to their fitted style. There will be no need to choose a smaller size.

Boys' thermals fit snug so they can prevent warm air from escaping from under your kid's clothing while they move during their sport's activities. It also makes the thermals more efficient when it comes to moisture-wicking. This is helpful during winter sports as your kid will sweat, which will help keep them as dry as possible. 

If you're worried about the snug fit and movement, remember that the fabric and the garment have been designed with a 4-way stretch for full flexibility. It should conform to most body shapes due to its stretchiness. Look for the correct length in your kid's arms. Which should be just past the wrist. 

Another way to check to make sure your boys' long johns are a proper fit, pinch some of the fabric, and pull it away from your kid's body. If it's too complicated, then this pair may be too small. Also, your kid can't get enough of a rolling movement with their arms and shoulders, then it's best to size up for a proper fit. They shouldn't be restrictive in any way. After all, you don't want them to hinder your kid's sport's performance. The air the thermals trap will be the insulator, so you don't want that warm air escaping too fast. Remember, if the thermal is too tight, it probably is, so it's better to size up.

Sports uniforms are made for the sport and not the weather. As the snow falls on the field, you want your kids to be protected from more than just a tackle from the other team. Thermals that fit snug are a perfect addition to the uniform and help protect your kids from cold-related dangers due to sweating in the cold.
