Excellent product!! I highly recommend
This product is absolutely excellent, and a fantastic value for the price. I purchased this for my son in law because he needed something to wear under his clothes when he rides his motorcycle during the cold months, and he is obsessed with this product. Not only is the product extremely comfortable, but it’s very soft, has the perfect amount of thickness, is comfortably warm, and fits perfectly under your clothes as it “stays in place” and doesn’t bunch up under your clothes like other products do. This product is made with a quality material that is durable and stylish. The sleeve length and pants length are perfect, not too short and not too long, hugging your body precisely like it’s designed to do. I’m so happy with this product that I’m going to purchase more in different colors. I highly recommend this product and would definitely purchase this product again.

Warm, Cozy, and Perfect for Midwest Weather!
I purchased two sets for an upcoming camping trip in the Midwest—where we can experience all four seasons in a single day! As a plus-size woman (size 14/16 with proportioned curves), I was unsure how a men’s set would fit since they’re not usually cut for curves. From the moment I put them on, I fell in love. The lining is incredibly soft and feels great against the skin, and the warmth is impressive. On our first night, the temperature dropped about 25 degrees and hovered near freezing—with a frost advisory for good measure. These thermal underwear kept me perfectly warm at the campsite. The next two days were brisk, around 40°F with wind coming off a small lake nearby, and I still slept amazingly well in these, a mummy sleeping bag, and a wool hat. Washing was easy, and after the first wash, the fabric and fleece quality stayed intact—no pilling or shrinkage. I’ll definitely be ordering more in every color to prepare for both Chicago winters and cold-weather camping trips!

Comfortable
Fit to size, comfortable, and kept me perfectly warm on a motorcycle ride in 45 to 50F weather.

Good thermal underwear for winter
The texture is smooth and comfortable, and light weight. But it's not tight enough with the skin so it will feel a little cold. Yet the size match and the quality if good.

Great quality
I purchased these as a gift to my husband, and I didn’t expect the quality to be so smooth and nice. In his words “ it’s warm but not overwhelmingly hot” and he just wears it around every day now. I reckon it would be a great base layer as it hugs the body and is light weight. Overall you will be pleasantly surprised! Get em!
