10 Best Mens Thermal Shirts 2025 in the United States

The Legendary Whitetails Men's Henley Long Sleeve shirt is a heavyweight thermal designed to keep you warm, featuring an 11 oz double-layer fabric made of 63% cotton and 37% polyester. This blend offers durability and a comfortable feel, although it may not dry as quickly as some synthetic-only options. The shirt has a casual, roomy fit suitable for layering under jackets or wearing on its own, with rib-knit cuffs and a classic three-button placket that contribute to its rugged style.

Its double-layer construction provides good insulation, making it ideal for cold days. While it doesn't specifically highlight advanced moisture-wicking or odor-resistant technologies, the polyester content contributes to breathability and durability. The seams are reinforced to withstand repeated washing and wear, supporting long-term use.

Extended sizes are available, including Big & Tall up to 5XL, offering versatility for many body types. The fit runs true to size for most, although some users might prefer sizing down for a closer fit. This shirt is well suited for those seeking warmth and durability in a casual, rugged thermal shirt for outdoor or everyday use rather than high-performance moisture management or odor control.

The Carhartt Men's Force Relaxed Fit Midweight Quarter-Zip Mock-Neck Shirt is a solid choice for anyone looking for a comfortable and functional thermal shirt. Made from a blend of 59% cotton and 41% polyester, it offers a good balance between softness and durability. Its midweight fabric is neither too heavy nor too light, making it versatile for various cooler weather activities. The relaxed fit and raglan sleeves provide extra room and freedom of movement, which is helpful if you’re active or layering. Moisture-wicking is a highlight here, thanks to Carhartt's Force and FastDry technologies that help pull sweat away and dry quickly, keeping you comfortable throughout the day. The UPF 25+ feature also adds light sun protection, which is a nice bonus. There's a zipper closure at the neck for easy temperature control, and a handy left-chest pocket for small items.

Some might find the polyester content less breathable than 100% natural fibers, and the relaxed fit may feel a bit loose for those wanting a more snug thermal layer. This thermal shirt balances comfort, moisture management, and practicality, making it a reliable option especially suited for those seeking durable workwear-style warmth with moisture control.

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.
