great product! This top does everything the label says. As a New Englander, and a regular hiker, I need more warmth and less moisture. It is also very comfortable against my skin, and the fabric is great for layering or wearing alone. I will be purchasing another for myself and one as a gift. October 6, 2011
Perfect for walking the dog in winter! I wear this just for walking my dog in the cold, winter months. The Omni-Heat works so well that I can get away with wearing just the baselayer and a light shell on top (mind you, I live on the coast, where winter temps only drop to about -1ºC). Still can't get over how WARM it keeps me!! Gotta love those little silver dots! November 29, 2012
Love the Women's Baselayer Midweight top I wear this under my sweatshirts when I'm outside on a chilly day as well as wear it for when I hike and run. It keeps me toasty without overheating. I plan on purchasing another one in a smaller size and different color. November 29, 2011
Omni Heat Really Works! I am typically a cold person and purchased a Columbia jacket last year with Omni Heat inside it and loved it. When I saw they came out with base layers with Omni heat inside, I had to get it. I love the way it feels, the materials breathe really well and it really does keep you warm. Great for all activities from snowboarding to hiking! It does run true to size as well. November 26, 2011
Thank God for Omni-Heat!! My first Omni-Heat product was the Whirilibird Parka in Bright Bluet. I needed something warm for sitting at my son's football game. Since then, if I can buy an omni-heat product, I will--my Bugaboo Boots were next. I love this product. The top adds a lot of warmth without adding a lot of bulk. There's a 4-way stretch to the fabric that makes it extremely comfortable. I tend to wear XL in Columbia tops, and it fits true to size. I live in NW Montana and snowshoe almost every weekend in Glacier National Park. While on the move, my base layer keeps me warm enough without needing my Whirlibird Parka. Once we stop for lunch and I am not moving around as much, I break out one or both pieces of the parka and start layering up. (which piece I wear depends on whether or not the temperature is above or below zero. I've been caught out on a trip where the temp drops to -20F without windchill). I love my omni-heat!! I have other baselayers from Costco that I bought last fall. They are being slowly replaced by new Columbia baselayers. November 19, 2011
Mostly good This shirt was comfortable except for the arms. The area of the biceps was too tight - I do not have big biceps. November 16, 2011
Great product! Yesterday wore it for the first time hiking to 10,000 ft and 30 degrees fahrenheit. Didn't have to wear my fleece just this baselayer, gloves, and hat. I tend to get cold easily and this product worked better than my expectations. November 12, 2011
Comfortable and Warm! I just LOVE this baselayer, it keeps me awfully warm and it's so stretchy I don't even feel it. And it's definitely not bulky, I can wear comfortably under practically anything else. November 4, 2011
amazing baselayer I wasn't sure if I should believe the hype on the tiny "magic dots" that Columbia is using these days but I'm a believer now! I have an outdoor job at a tree nursery in Montana and cold fall/winter mornings are real rough. I wore this shirt with my usual layers and layers in 26 degree weather and had to take things off because I was sweating! It was so awesome not to need a lot of bulky clothing to stay warm. This is the way of the future, I predict you'll see this technology on winter clothing everywhere in 10 years. November 3, 2011
Love this shirt! Was looking for a base layer for running now that the weather is getting colder in Michigan. This shirt works great! I have only used it a few times, but it has definitely kept me warm. Would recommend it to anyone. October 27, 2011
