Best Thermal Underwear Tops for Men of 2025

"I appreciate the layer of warmth during fall and winter. The fabric is soft and stretchy, and I find them comfortable enough for daily wear."

"I ordered multiple shirts, and while the first one was perfect in every way, the others were not the same quality. Disappointed that I can't get more of the good ones."

"My husband is very pleased with the fit and says they feel soft against his skin, providing him with warmth during the chilly days."

"I ordered a size larger because I wanted a looser fit, but the shirt is still quite tight, making it tricky to put on or take off. I'm hoping it stretches a bit, but if it shrinks in the wash, it might end up as a rag in the garage."

"For the price, this shirt is perfect! The fit, color, and warmth are all great. My mother loves it and finds it very comfortable. I will definitely buy again."

"I bought these to sleep in, and I’m really pleased! As someone who is 5'11", the length for both the sleeves and the shirt is just right. They are cozy and reasonably priced, making this purchase a great choice for me."

"I recently purchased these thermal compression shirts for coyote hunts, and I'm truly impressed! The fabric is soft yet durable, providing great insulation without feeling bulky. They fit snugly but aren’t restrictive, keeping me warm during my runs in cold weather. The moisture-wicking feature is a lifesaver, keeping me dry even during intense all-night hunts. The 5-pack is a fantastic value, and I’m rotating them regularly. Highly recommend for anyone needing warmth without bulk!"

"With winter here, my husband needed thermal wear urgently. We found these and they did not disappoint. The quality is thick and soft but not bulky at all. After washing them before wearing, there was no shrinkage, which was essential. They add warmth without being too hot. We highly recommend these!"

"This product is incredibly warm and feels durable for the price. If you're uncertain about sizing, I suggest going a size up. It’s not bulky but still offers warmth. Really good purchase for the cost!"

"I bought one of the black shirts on sale for about $9.00. At 6 ft. tall and 150 lbs, I typically wear a medium but got a large. It fit perfectly when it arrived, but it shrunk a little after washing and drying, making it a bit snug and the sleeves shorter. Next time, I will air dry it to avoid shrinkage. Overall, it's a very comfortable shirt that keeps me a bit warmer."

"I'm 5'10" and weigh 380 lbs. I ordered a 5x size, which fits well in the arms, chest, and neck, but it's just too short. When I lift my arms, the shirt rides up above my belly button! While the fabric feels nice, it doesn't block wind well or serve as a standalone layer in the cold. However, it's comfortable as part of a layered system. I might send it back."

"I find these shirts to be warm and comfortable, making them great for use as PJs in cold weather. However, I did notice they run a bit small."

"I ripped open the package and threw them on—these fit perfect!! I'm 6'2", 236 lbs, and the XL worked just fine. They feel really soft and warm! I love them so far and plan to order another set this week! Update: I still love these thermals sooo much! Just a heads up, they do shrink a tad in the dryer, so I bought the XXL and they are just perfect!"

"I found these to be comfortable and warm, exactly what an outdoor person like me needs. I haven't noticed any shrinkage of note. Overall, a great purchase!"

"I’m very pleased with this top. It’s good quality and very warm. The size chart was accurate, providing a snug fit. If you prefer a looser fit, I recommend going up a size. I’m definitely buying more when they come back in stock for my size!"

"These shirts are incredibly warm and soft, and the fit was just right for me."

"I bought these for my boyfriend who rides his motorcycle year-round, and he thinks they are very soft and warm!"

"The fit was perfect for my husband, and he absolutely loves them!"

"I live in the Midwest, where temperatures can fluctuate dramatically. These thermals are some of the best I’ve purchased. I have several colors and even wear them under dress shirts without feeling bulky. They do a great job of keeping me warm at a much lower price."

"I bought the XL size expecting some shrinkage, but after a few washes, it now fits more like a medium. The fit is tight around my chest and shoulders, and the sleeves are too short. I recommend going two sizes up for a better fit after washing."

"The material of these shirts is very good quality, and the sizing is just right."

“I was impressed with the quality when I received them as a Christmas gift. They didn't shrink after washing, and the colors matched perfectly. A well-used gift that kept him warm without being too thick. Great purchase!”

“As someone who spends time painting and creating, I find these men's XL shirts perfect for comfort and breathability. They're mostly cotton and become softer with each wash. At only $8 a piece, they are my new winter wardrobe at home!”

“I had to go one size up for the sleeve and waist length, but the seller's customer service was fantastic and made the exchange quick and easy for me.”

“I find these thermal shirts comfortable. They run a bit small, but overall, they're nice.”

“I was disappointed because the top feels very thin and runs large. The finish at the bottom isn’t my favorite either.”

“I purchased these for my son, and they were perfect for keeping him warm at work and night. Thanks for the quick shipping!”

"I thought the low price was appealing, but the fleece lining is so thin that I doubt it can keep anyone warm in cold weather."

"I bought these for my husband to wear while working on the car in the garage at night. He finds them extremely comfortable and soft, and they surprisingly manage to keep him warm. However, I wish they offered larger sizes for the rest of the family. Just one downside for me is that they are handwash only, which I really dislike."

"When I received the shirts, I noticed that the collars were much wider than what was shown in the pictures, and they feel like they aren’t designed for men. Also, the length is a bit on the short side."

"I found several little holes in every shirt, as if moths had gotten to them. I wear them under other shirts while walking my dogs, so I didn’t bother returning them. Just a heads up that they come 'holey,' and I’m not talking about the holy ghost."
