Soft and cozy
I’m really happy with this thermal underwear set. The material feels soft, comfortable, and warm without being overly thick. It fits nicely under clothes and is perfect for layering during cold weather. I also like that it’s flexible and easy to move around in. It’s a great basic set to have for chilly mornings, traveling, or outdoor activities.

Amazing!
Bought these for my ski trip back in March and they worked amazing!! I was warm the entire time wearing these under my ski pants and coat. Super soft and super warm. Fit perfectly. Very durable.

Warm, soft, and perfect base layer for cold weather
This thermal underwear set is super soft with a cozy fleece lining that keeps you warm without feeling bulky. The fit is comfortable with good stretch, making it easy to layer under clothes for all day wear. The quality feels solid and it holds up well after washing without losing softness. It’s been especially great for cold weather and outdoor activities where you need reliable warmth.

Love these great, non ribbed set of Thermals!
Non ribbed thermal top and bottom, which worked well on my Alaskan cruise! Kept me warm without the bulking. Worn under my yoga pants and jeans! Great value!

If you have fabric sensitivities avoid.
They are warmish, not as warm as the cheap long johns I got at Walmart. The fabric has polyester in it and is itchy and scratchy. They are not the worst ever, but nowhere near the best either. They are super thin, fit was ok. Overall, I'd rate them slightly below average. In the future, I'd just get the super cheap cotton ones at Walmart and skip these unless polyester is your favorite. I would not rate them as thermal as someone who spent half her life in Wisconsin. They barely kept me warm during a cold spell in Arkansas.

Comfy
Very soft and comfortable thermal under garments. Their cozy, though they could be just a little bit warmer. I was worrying them while in Iceland, and they helped keep me warm, but as I said, they could be slightly warmer. I do like the fact that they are very thin, which meant they fit underneath clothes nicely. I gave four stars instead of five just because as a thermal underwear set, I do believe they could be warmer.

Soft and warm
This is the second set of these I’ve had, the first I ordered in a Medium as I’m in between sizes. They’re comfortable and nice for lounging in but too big to wear under anything, so this time I got a Small. These are a much better fit so I’d definitely suggest sizing down if you’re unsure as these do run larger than expected. The material is soft against your skin and not too thick, it’s practical under another layer or two and at around £20 a set a really good buy - I was paying that just for a thermal top. They’re nice and stretchy and they’re long enough in the leg and body to fit me at 5ft 8in. I’ve washed and dried the first set a couple of times and they don’t seem to shrink at all. I’d definitely recommend these!
