Women’s Midweight Stretch Baselayer Tight is rated 4.6 out of 5 by 29.
Rated 5 out of 5 by from Great I purchased these thermals for a trip to Yellowstone early in the year. I wore them under the Saturday Trail Stretch Pants on hikes and it couldn't have worked out better. They are thin enough to easily fit under pants, and stretchy enough for me to hike in two layers of pants without being constrained. I stayed warm in temperatures in the 30s while hiking, and hiking in snow. When it warmed up, it wicked away any sweat and kept me comfortable. I would definitely buy it again and highly recommend!

Rated 4 out of 5 by from Great leggings I was concerned about buying online, but when they showed up they were perfect. The reflective material really keeps me warm and doesn’t feel any different than normal legging material. They are super stretchy (not loose) and fit very complimentary.

Rated 5 out of 5 by from My favorite Leggings for around the house These leggings are PERFECT for around the house on weekends and evenings! They are so comfortable, the fabric is very soft and they fit loose and lovely. I intend to purchase a few more pairs!

Rated 1 out of 5 by from Disappointed Main reason for the poor review is the poor construction for the high price. I had these for 5 weeks and only wore a couple of times and the stitching between the elastic band at the top and the pant separated. I now have a 2 inch hole between the band and the pant. Very disappointing. Other reason, was I was hoping to wear as a standalone on walks with my dog, but they are not as warm as I was hoping for from a mid-weight legging. Regular knit leggings are warmer.

Rated 5 out of 5 by from Great tights! I bought these to use as long underwear while I volunteered outside at Super Bowl 52 in Minnesota. They did not disappoint! They are thin and super comfortable. They were so comfortable I forgot I had them on. I love the omni-heat feature. I have boots and jackets with the "silver lining" as I call it, and they are all super warm. I specifically bought these because of the omni-heat feature.

Rated 5 out of 5 by from Keeps me very warm! I originally purchased these for a winter trip to Shenandoah but found myself using them under my work clothes when VA got very cold weather. I work outside and these fit wonderfully under my clothes and kept me so warm and most importantly dry. Highly recommend! Great product for a good price. For reference, I’m 5’2”, 145# and size M fit great.

Rated 5 out of 5 by from Love the OmniHeat Feature I drive 35 km to work on rural roads so wear my winter underwear all the time. I can put these on at 7am, wear them all day at work in various temperatures and when I take them off in the evening, my underwear is NOT damp from sweat and I am not feeling chilled. I love them. In fact, I tried to buy some for my large husband but I couldn’t find any in his size. I also have a winter jacket with the OmniHeat feature and love it, especially when it’s cold & windy.

Rated 5 out of 5 by from Keeps you warm! I wore these for the first time yesterday as a base layer in 40 degree weather and raining. I feel like they really did help with keeping me warm. I do feel like they are a bit longer than other Columbia leggings I own. However, I do have short legs so that is normal for leggings to be long on me. I will more than likely buy the other color sometime soon.

Rated 3 out of 5 by from Good base layer This legging is really warm and yet also very breathable. However, the waist is very high, and the elastic band is sharp- it could be a lower waist for those of us that don't want to keep it folded down, and the elastic at the top could be covered and softer. Good materials overall, this is on its way to becoming an excellent product. Could we see a version in this fabric that fits more like a yoga pant waistband instead of a traditional tight?

Rated 5 out of 5 by from BEST EVER! I love these leggings so much I cannot express it with words. I wear them backpacking, climbing, hiking, camping, to work, under dresses, and to bed. I've worn them in below zero temperatures (with other layers) and on cool summer days. I own four pairs. Normally I order a Columbia size small, but I like the leggings in a medium just so the elastic waist doesn't cut into me- it does leave the legs with just a little extra space- but I like it that way. I also was initially frustrated that these didn't come with a "short" inseam since I'm 5'2" but because of the design it doesn't matter, they fit great. They are extremely durable. My first two pairs were purchased almost 4 years ago and while thinner than they used to be, they don't have a single hole. This is impressive because I wear them to climb and canyoneer and thus drag them over rocks regularly. These leggings are warm and stylish and extremely functional. You need 5 pairs, just like I do!

Rated 5 out of 5 by from Great Pants for the backcountry These keep me warm but are also thin and light weight. I am happy with these!

Rated 5 out of 5 by from Best tights! I originally got the capri version of these tights and wear them all the time. I love them - they even held up when I was chased by a herd of cattle in the English countryside! Got a little torn and scratched, but they're still functional and warm. They fit perfectly. The full length is a little long on me - I got a medium because my backside and legs are a bit big, but I'm 5'4" so they kind of slide down and bunch up around my ankles. All tights that aren't compression tights do this to me. These are warm, very comfortable, durable, and just what I need to run/hike/paddle in the Southeast in the Fall and early winter. They also work great as a baselayer when skiing.

Rated 1 out of 5 by from Not warm at all They feel like regular but good quality tights/ leggings. I don't recommend wearing them in frigid weather, but as a base layer for slightly cold weather is ok.

Rated 5 out of 5 by from I Have Four Pairs! These leggings are perfect for everything. They're light enough to wear around the house, under skirts, and to bed. They're warm enough to wear as a base layer for outdoor adventures. I've worn them in every weather condition and they have kept me toasty. I have worn them climbing many times and bushwhacking and they don't have any holes in them (yet). They're sturdy and attractive! The sizing is good. I am usually between a small and medium and was happy with the medium in this product.

Rated 5 out of 5 by from Stretchy, warm and comfortable! Love, love these tights! I work and play outside throughout the full Wisconsin winter. These base layer tights are my go to for keeping warm while active outside. They are extremely comfortable and slip easily under a pant layer. Love them and plan to order more!

Rated 5 out of 5 by from This product has great features I have worn this item once and I felt comfortable wearing them. There was no bulky feeling like some other products. I work outside and they kept me warm. I had ease of movement, no constricting around the waist, and I could hardly tell I had them on. Great product

Rated 5 out of 5 by from Feel great! These are really comfortable and don't feel bulky. They are plenty warm enough when you are being active like cross country skiing. Not quite warm enough when snowmobiling due to the lack of physical activity and wind from driving. Overall they are a really good buy!

Rated 5 out of 5 by from Love them~! A Great product! Decided it was time to get myself a pair and I just love them. Great for taking the dog out for a winter walk or when shoveling, etc to keep the chill out. Great job Columbia!

Rated 5 out of 5 by from Omni Heat I love the Omni Heat products. After purchasing ski pants with the Omni heat my wife and I have purchased full Omni Heat gear including base layers, jackets and hat. We are California skiers so the range of temperatures is wide and the Omni Heat keeps us warm without a lot of layers as well as not overheating.

Rated 5 out of 5 by from Fun and warm! Bright Plum XL, I'm 5'6" normally a size 18-20 in pants, they were really comfortable and stretchy and warm for a day in the snow (worn under the Anytime Outdoor pants), and did the anti-smell thing so I wore them as leggings under a dress the next day. I love the bright color too!
