10 Best Mens Thermal Shirts 2025 in the United States

The TELALEO 5 Pack Men's Thermal Compression Shirt is made from an 85% Polyester and 15% Spandex blend, which provides a snug fit and some stretchiness. This material is effective for locking in heat and keeping you warm, an essential feature for cold weather activities. Additionally, the shirts are fleece-lined, enhancing their warmth retention properties. The moisture-wicking fabric quickly draws sweat away from the skin, ensuring you stay dry during workouts or other physical activities. This is particularly helpful for people who engage in high-intensity exercises or outdoor sports in colder climates.

The shirts are designed with a versatile use in mind, suitable for a variety of activities like cycling, running, and even ice hockey. However, the material may not be the best at odor resistance, as synthetic fabrics can sometimes retain smells after sweating. Another potential drawback is the care instructions; while the shirts are machine washable, they should not be bleached or ironed, which adds a bit of maintenance consideration. The seam construction appears to be solid, providing durability and comfort without chafing.

The weight of the shirts is relatively light at 1.2 pounds for a pack of five, making them easy to layer under other clothing. This thermal shirt pack is a cost-effective option for those looking for warmth, moisture control, and versatility in their base layers, though users should be mindful of potential odor retention and specific care needs.

This Carhartt men's thermal shirt is made from 100% polyester with Force technology designed to wick moisture and dry quickly, making it good for staying dry during active or cold weather use. The fabric is lightweight and comfortable, which suits layering under other clothes. It also has odor-fighting properties to keep you feeling fresh after extended wear. The flatlock seam construction is a nice touch as it helps prevent chafing, which is important for comfort during long days.

A thoughtful feature is the concealed thumb loop, which can keep the sleeves in place when layering or moving around. Fit-wise, the advice to size up if you're between sizes is useful since the fit can run snug, typical for performance thermal shirts. The tagless label adds to comfort by avoiding irritation on the neck. Because it’s 100% polyester, it may not feel as soft or breathable as natural fibers like cotton or merino wool, and some people might find it less warm on very cold days without additional layers.

This shirt serves as a solid choice for men needing a reliable moisture-wicking base layer that moves sweat away quickly and reduces odor, making it ideal for work or casual wear in cool to moderately cold conditions.

The Under Armour Men's ColdGear® Base 4.0 Crew LG Black thermal shirt is designed for extreme cold conditions, making it an excellent choice for outdoor activities in harsh weather. One of its main strengths is the material; it's made from a blend of 78% Polyester and 22% Elasterell, ensuring durability and flexibility. The 4-way stretch construction allows for easy movement in any direction, which is particularly beneficial for active users.

Additionally, the soft, brushed grid interior effectively traps heat against your skin, providing substantial warmth and comfort. Another great feature is its moisture-wicking capability, which ensures sweat is quickly drawn away from your body, keeping you dry. The shirt also dries very fast, enhancing comfort during prolonged use. The UA Scent Control Technology is a valuable addition, helping to manage odors and keep you feeling fresh.

However, the product weighs 1.15 pounds, which may be on the heavier side for some users, especially if layering is needed. Some might find the fit to be snug due to the performance-oriented design, which could be less comfortable for casual wear. While the seam construction isn't specifically detailed, the quality and reputation of Under Armour suggest that it should be robust and well-made. Machine washability adds convenience, although care should be taken to follow washing instructions to maintain the fabric's performance. For men needing a high-performance thermal shirt for extremely cold environments, this could be a strong option, but casual users might find it more than what they need.
