Great product. Ordered another set.

Great price, fit and functionality. My grandson lives in the far Northern States and these were a Christmas Present for him. He liked them so well and used them on a daily basis that I order another set to be delivered tomorrow. The fabric was of great quality and functioned well for the cold weather. He says they are very comfortable especially the crew neck. No so much with the turtle neck one. Read more

Quality product

Outstanding heavyweight base layer. Expensive ... but worth it to stay warm in extreme cold conditions. Quality construction so it should also last a long time to get your money's worth. Wish that Amazon offered in tall sizes. I am 6'2" and ordered the large ... fits well, with sleeves a bit short .... but a very long bottom. Highly recommended. Read more

Always amazing

I wear these daily and absolutely love them. Got one with a seem that came undone and almost returned it but it was the cheapest they’d been. I kept it and canceled the return and I’m wearing it right now. They’re super durable, super warm and comfortable. These are my go to base layers! Under armor hits it out of the park again!

Best product out there!!

Best for cold weather work. I work in the oilfield and this worked great throughout the winter. I wouldn’t suggest use if weather is above 40 degrees because you’ll overheat. Great product and I will purchase more!! Make sure to get the bottoms as the set. Read more

Super Warm!

I've been a huge fan of Under Armour for years (at least 15+). I'm impressed with how warm this base layer and the matching bottoms keep me, and how comfortable they are. What a great upgrade from my base layer 3.0 I had. I would say the price is a bit high for what they are though. $200 for the set is a bit outrageous. Read more

Warm and comfortable

Warm is an understatement. I ordered 1 size down to ensure a comfortable fit that wasn’t bulky under my clothes and it worked out perfect. After a significant weight loss winter hit a bit harder than it has in the past and this kept me warm and comfortable at football games and in the field. Read more
