  • Not your dad’s thermals.
Color: 1-black Size: Medium
Perfect fit. Comfortable and form-fitting. Great as pajamas, under clothes on cold days, or just lounging around the house.

  • I like this set a lot
Color: 1-black Size: Large
Sizing was spot on, the cloth is a great thickness for warmth without a lot of extra material. It is breathable and soft. Haven't tested it in very cold conditions yet, but its nice for some chilly fall activities thus far with minimal outer layer over top (coaching sports on a windy field, going to a football game, etc) ... show more

  • Great Buy for Thermals
Color: 1-black Size: X-Large
Great fit! Keep me nice and warm. I bought a bunch of different brands of thermals. These are the best by far. Good quality as well.

  • Very warm base layer!
Color: 3-black Size: X-Large
Incredibly warm during an elk hunting trip in October this year. Left camp most mornings with just these and a pair of hiking pants on for the steep hike out to my spots and kept me more than comfortable in mid 30 degree temperatures. Not as Moisture wicking as it held in moisture and gave me a sweaty back, but didn’t pick up too much of a scent after a week of camping as compared to some of my other clothing, and dried out super quick over a wood fire stove. Very thick and almost too warm if it warms up past 40 degrees with moderate to heavy activity, so have a plan to change layers throughout the day. 4 out of 5 stars due to the snug leg design which helped them fit under a shell pant but they felt like they were prone to sliding down throughout the day, maybe should’ve sized up for a better fit but these will still work. ... show more

  • Warm
Color: 1-black Size: X-Large
These were well worth the money. Thin yet very warm. I used them as a base layer for November bow hunting in Iowa. Very comfortable as well.

  • Nice fit
Color: 1-black Size: 4X-Large
Great Thermals, sizes are correct pants fit good. The top is more compressed/snug fit, but it is a first layer, I can deal with it. Light weight but warm. I will buy another set.

  • Warm and comfortable
Color: 1-black Size: Large
Really good and super warm. Is still in the 40s and some 30s but I can feel is super warm and comfy

  • Much warmer than they seem
Color: 1-black Size: 4X-Large
These are so thin and stretchy I was concerned about them being warm enough. They were fine. I couldn't feel the seems at all. Size was right, they fit well. They did a great job of wicking.
