10 Best Men's Thermal Long Sleeve Shirts 2025 in the United States

The CarharttMen Loose Fit Heavyweight Long-Sleeve Logo Sleeve Graphic T-Shirt is made from 100% cotton, which makes it comfortable and durable. This shirt features a rib-knit crewneck and cuffs, providing a snug fit around the neck and wrists. The side-seamed construction helps minimize twisting, ensuring the shirt maintains its shape throughout the day.

Additionally, the shirt has a tagless neck label for added comfort and the Carhartt signature logo printed on the sleeve, giving it a stylish appearance. It's designed to be machine washable, making it easy to care for, and it uses a pull-on closure for convenience.

The Hanes Men's Beefy Long Sleeve Henley is made from a soft and durable 6-ounce ring-spun cotton fabric, offering a comfortable and substantial feel. This fabric weight is heavier than typical lightweight shirts, making it suitable for cooler weather, although it does not include specialized thermal or moisture-wicking technology, so it may not be ideal for active moisture control.

The shirt features a classic Henley neckline with a three-button placket, adding a casual, stylish detail that distinguishes it from regular crew neck thermal shirts. Fit options include Big and Tall sizes up to 3XL, which help in finding a good fit, with a standard, relaxed cut rather than a slim or performance fit. Traditional set-in sleeves are used for solid colors, ensuring comfortable arm movement, though the seams are not specifically designed to minimize chafing during intense activity.

Care is straightforward since the shirt is machine washable and easy to maintain. This Henley provides solid warmth and comfort with heavier cotton, making it a good choice for casual wear in cooler weather rather than for high-performance or layering purposes.

The Under Armour Men's ColdGear Armour Compression Mock is designed to keep you warm in cold conditions while managing moisture effectively. Its dual-layer fabric features a brushed interior for warmth and a smooth exterior that dries quickly, which is great for active use when you might sweat. The material is 100% knit and includes stretch-mesh panels on the back and underarms to boost ventilation without losing heat. This helps regulate your temperature, so you stay comfortable.

The shirt has a very tight compression fit, hugging your body closely like a second skin, which can improve movement but might feel restrictive if you prefer looser clothes. Seams are placed thoughtfully to avoid irritation in spots that rub a lot, and the mock neck provides extra coverage and warmth around your neck. Weighing about 1.4 pounds, it’s lightweight enough to layer under other clothing.

Since it’s made to dry fast and wick away moisture, it’s suitable for active men who need thermal wear that doesn’t get clammy. If you don’t like tight-fitting shirts or want a more relaxed fit, this might not be the best choice. This shirt is a solid option for those looking for a warm, moisture-managing garment with a sleek, athletic fit.
