Understanding Long Johns

Long johns, also referred to as thermal underwear, are designed to provide warmth in cold conditions. Often made from various materials such as cotton, wool, or synthetic blends, they are an essential item for layering. Long johns are typically worn under regular clothing as a base layer to trap body heat.

Should You Wear Underwear Under Long Johns?

The Case for Wearing Underwear

Many people, including experts from sites like decideoutside.com and freedomresidence.com, endorse wearing underwear beneath long johns. This provides an additional layer of insulation and helps reduce skin irritation, particularly during physical activities. By doing so, you can also increase the longevity of your long johns, as they will require less frequent washing.

The Case Against Wearing Underwear

On the other hand, some argue that wearing long johns alone is sufficient. As noted by famewatcher.com, long johns are inherently designed to function as underwear, so adding another layer may feel redundant. For those engaged in vigorous outdoor activities, going commando can enhance mobility and minimize chafing.

Types of Underwear to Wear Under Long Johns

Cotton Underwear

Cotton is a breathable and comfortable option. However, when it comes to thermal insulation, it may not be the best choice, especially in wet conditions. Cotton retains moisture and can lead to chills.

Moisture-Wicking Underwear

Moisture-wicking fabrics, such as nylon and lycra, are ideal for those who plan to be active. They pull sweat away from the body, keeping you dry and comfortable throughout your activities. This option is highly recommended for colder climates and intense workouts.

Compression underwear provides support and can enhance performance during physical activities. While not as warm as thermal long johns, they can be beneficial for sports enthusiasts looking for muscle support.
