I work outside in the frigid temps. I have ordered Heat Holders products for a couple of years now. These base layer bottoms definitely help keep me warm outside, I also wear them inside as pajamas. I only gave 4 stars because they're not as thick and warm as the pairs I purchased last year. The socks haven't changed this year but the tops and bottoms seem less thick than last years type. That being said, they're still very warm! Thank you for great products!

I ordered the medium bottom. These are very comfortable and warm to wear however the sizes are off, they fit more like a small, they were a little tight at the waist and the leg length was a little short. (I'm 5' 10" 140 pounds) I ordered the large and they fit perfectly, the fit and length was right. Before you buy order the next size up.SIZE REAL SIZESmall = Extra SmallMedium = SmallLarge = MediumXLarge = Large

These leggings are so soft and comfortable. They are reasonably lightweight but provide extra warmth in 20 - 40 degree weather. I'd buy another pair if I lived in this kind of climate.

My husband likes these Heat Holders Men's Warmest Thermal Pants. George is a retired rancher from Texas. Couple of times he experienced minor frost bite. George has a slow heart rate so have difficulty getting the blood flow quick enough to warm is arms and legs. He is cold nature and the fear of cold weather is high. This product has been a hugh help and keeps him warm. Presently he has two full sets. Thank you. His wife, Opie
I bought t mid range long underwear great fit and comfortable ... then bot t long underwear shirt for colder wx ... perfect fit. Then ordered t matching longunderwear pants for colder wx ... ordered t same size ..too small dont understand it. I'll just have to loose weight to fit into it... the previous 3 pieces... same size, fits perfect ... o love your products, especially t socks...12 christmas gifts to family were a hit. I use t socks like slippers. Thanks
Love the texture. Most guys might not pay attention; but, I’m an old geezer [82 years young], walking is my primary exercise, year-round, and that has to include comfortable warmth when we get to mid-winter. Folks think New Mexico is going to feel like the Sonoran Desert; but, not when you live in a community just outside Santa Fe in a valley at 6300’ altitude. It’s almost as cold in the winter as it got to in my childhood back in New England.These aren’t any thicker than the brands designed for winter sport I’ve used the last few years; but, the textured design is definitely going to be warmer come January and February. I tested them same days and alternate days against our Autumn temperatures and the other two brands I’ve warn recent years and these always felt ... MoreLove the texture.

I tested them same days and alternate days against our Autumn temperatures and the other two brands I’ve warn recent years and these always felt warmer on my walks, windy or not. Sunny afternoons, I wore them under walking shorts, Dark, cold mornings down to almost freezing, I’ve worn them under Amazon’s standard cotton sweat pants. When we get to the coldest mornings, I’m figuring on these as first choice under heavier cotton-poly blend sweats I wear mid-winter.
The Base lower tops and bottoms were absolute fantastic. He loved them and wore them fishing the other night at 26 degrees and in water. Was NOT cold at all. He also has the socks. Great items. I recommended these to his friends. Hope they get them. So very nice and the material is excellent
These were well received! My husband is a veterinarian and works on a lot of horses in cold barns throughout the winter. These base layers kept him nice and warm without being too bulky and too hot to wear driving from barn to barn. Also loves them for chores around the farm in the cold weather. Hoping to add a pair of the lightweight version this year for the days that are not super cold!
They’re just what I expected from Heat Holders and they’ve, so far, been more than a match for an unusually chilly Minnesota winter. I’ve not had any other thermals that have performed so well.I recently ordered a top in the large size large and I probably should’ve requested a medium. (I was probably thinkin’ like a husky Canadian — which I’m not).I’d really like to see 'em in different colors.I also have an issue with the durability of the socks and gloves I’ve ordered — which have been many — but I’ll address that at a later time.Janook of the North
Just ordered these recently. Glad I did...the very softest, most comfortable thermals ever, and fit well. I feel like they are hugging my legs and keeping me warm. Can't wait to buy more and to try the other two weights, and will order some tops as well. Have been happy with everything from Heat Holders...gloves, hat, blanket, socks and now thermals. A real fan!!
