Rated 4 out of 5 by from A tad roomy I am a fairly petite person at 5'1" with a slender frame. I was worried these would be more spandex-y, so I purchased them in a small. On the contrary, they're much less fitted than I imagined, so they're actually a little too roomy on me. If you're on the petite side and want a tight that hugs your body more to retain heat, I'd say to go down a size. Otherwise, very comfy and warm!

Rated 5 out of 5 by from I love this product! I get cold hives so I need to keep warm in the colder months. I love hiking and being outdoors so I have a couple pairs. I would recommend these to anyone who wants to stay warm.

Rated 5 out of 5 by from Highly recommend I got these on Black Friday this year and I am so glad that I did! I usually exercise at night and they have been great for weather in the high 40s. I'm 5'6 and the medium fits fine. A little long but I just bunch it up at the ends and it's not noticeable and looks fine! Keep me warm and I am going to make them my go to for a hunting base layer next season. Awesome product.

Rated 5 out of 5 by from Great Had to purchase these online because southern states don't get shipped this kind of cold weather technology so I was worried. I took these on my mountain trip and loved them. They kept me warm on my trip. Just keep in mind they will really make you sweat if it's not cold. Best if the temperature is below 50. I highly recommend this clothing line to anyone who needs to pack warm but not bulky for their trip. Love them got a coat hat gloves scarf with the omniheat tech as well.

Rated 5 out of 5 by from Perfect for the cold blooded I sadly anticipate the freeze every year come October... Anything 60 F and below makes my hands and feet icy to the touch. I love being outdoors, but the feeling of slowing turning into an ice cube isn't really my favorite. Last year, I bought an Omni heat jacket and LOVED it. A game changer for sure. I sized up (medium) and it is a large on me (xs/s), but I wouldn't change it for the world. This year, I realized that Columbia also sold Omni heat base layers and I decided to try. Gosh! I can't believe the difference! I'm going to get another top before I finish preparing for winter this year, but I'm so excited. I can enjoy the outdoors all year around this time. :)

Rated 4 out of 5 by from Great leggings I bought these to wear under warmer clothes when outside for extended periods of time in the winter. Unfortunately in Wichita, we have had a very mild winter so I can't rate them based on warmth. However, they are super comfortable and I find myself wearing them around the house for casual and comfort wear.

Rated 5 out of 5 by from This product has a great function that protects you from the cold. This product is used for when I work in cold temperatures at work.

Rated 5 out of 5 by from Warm & comfy These tights feel really good on and fit great. They are warm in 20+ degree weather, but when it gets into the teens and windy they were not enough.

Rated 5 out of 5 by from I love anything omni heat! I changed my mind on the size based on reviews on this and other sites. I should have gone with the smaller size which is now unavailable. Better too large than too small though.

Rated 5 out of 5 by from Great with layers I love these and have 3 pairs. Last winter we got some snow and it was cold, and they were great. I went out on my birthday which is at the end of December with just these and some shorts and my legs were a little cold only if I was standing still but not very. But if you wear them under pants they are perfect! I totally recommend if you have to go to a fancy event and want to wear a dress to wear these underneath, cause they will help keep you warm, and once inside you can take them off and stuff them in your purse, they are small when folded up. I love them, you won't regret buying them. Size: I usually wear 4 or 6 in pants (5'4 and 135lbs), and decided to go a size up cause the small gave me a muffin top, medium goes to about my belly button when on, but is the perfect fit for me.
