Women’s Trail Summit™ Half Zip Shirt is rated 4.7 out of 5 by 22.
Rated 5 out of 5 by from Exactly as advertised. I love this shirt - it keeps me warm, fits comfortable - snug to keep in the warmth but not too tight. Would definitely recommend this shirt and would buy again (if there were any left - but there aren't!).

Rated 5 out of 5 by from Warm Lightweight Top! Purchased this top after a trip to Iceland with a friend who wore same, love the zip neck, finger holes in sleeves and the thin layer with the "heat" element to keep you warm eliminates an extra layer in 38-45 degree weather. Fit true to size small. Nice fabric, lightweight.

Rated 5 out of 5 by from Great Quality! This half zip is perfect for layering and was a bargain! Despite the fabric, it doesn't fit too snug and that's something I look for.

Rated 4 out of 5 by from Great basic for running This is a great basic for running in cooler weather. The top is on the fitted side so it won't cover any flaws in the midsection. It is lightweight and confortable while still offering a bit of warmth. On sale, this purchase is a no brainer. Buy two

Rated 5 out of 5 by from Fabulous This superb quality product is consistent with Columbia's high standards. The zipper, fabric and stitching are remarkable. The fit is as described. It wears well, provides warmth without smothering. After a wash and quick dry, it looks brand new. Great product, as always from Columbia. Thank you for being so reliable and consistent.

Rated 5 out of 5 by from Perfect for Wisconsin summer nights I love this shirt! It is perfect for the cooler summer nights, and will be great for the fall/winter! I ordered a medium, usually wear small/medium. It is a little big, but that will be perfect in Winter.

Rated 5 out of 5 by from Excellent product! The quality is wonderful. This is the type of pullover I was looking for. I am on vacations using it in snow and it kept me warm. It is perfect for outdoors! I bought only one just to try it but definitely I will buy more of the same kind of material for my next vacations!

Rated 5 out of 5 by from Great Shirt I'm going to Iceland this coming Winter. Needed a shirt that would keep me warm. This shirt is beautifully made, fits great and I absolutely LOVE the thumb holes. When I tried it on, I was pleasantly surprised. The Omni-Heat does the job and I just know that I will be toasty warm during my photo shoots. I plan to wear it over long johns and under a down vest plus coat. I am seriously thinking about purchasing another one. I am 5'9" and 155 lbs. I highly recommend this shirt.

Rated 5 out of 5 by from Wonderfully warm top I have an Omni-heat jacket with I absolutely love and was so happy when I saw that these half-zips were also Omni-heat! It keeps you so toasty warm without being TOO hot. I wish it came in more colors, I'd get one of each!

Rated 5 out of 5 by from LOVE LOVE LOVE THIS SHIRT! I just got hiking fever and was so lucky i found this shirt for my hike to Yosemite. The heat technology in this shirt kept me warm while hiking in very cold weather but was light enough that i didn't feel constricted. It was very stylish and I love those little thumb holes at the end of the sleeves. And the material is very high quality! It was a bit large on me but I'm very petite for anyone else i think it would be pretty true to size.

Rated 5 out of 5 by from Warm, light weight and perfect for cold weather adventures! I live in Maine's Northwoods where the winters are long, windy and frigid. I bought this to wear hiking and I love it!! I stayed toasting warm without heavy layers. Its thin, lightweight and with the Omni-heat technology, perfect for any outdoor activity as a second layer. Highly recommend!!

Rated 4 out of 5 by from Prefer to wear in warm weather conditions I really wanted to give this shirt 5 starts. I sweat easily (I know it's good for the body, but in the winter I get an EXTREME chill afterwards). Therefore, I'm not sold on this pairing of wicking and OmniHeat functionality; in weather that is warmer, then yes -- in the wintertime, no. I was so uncomfortably chilled, I couldn't wait to get inside and pull this soaking shirt off of my body. When I exercised with it in 60's weather, it was bearable.

Rated 5 out of 5 by from Excellent shirt, especially for cold blooded people & cold tempI've boughts Let me start by saying that I'm disabled, low weight, & 1 thing I have is Reynaud's, which affects how my body reacts to temperature, & I have more problems with cold, not just with Reynaud's, but with some of my autoimmune diseases as well, so keeping warm is essential to stay warm! I've bought many Omni-Heat shirts, jackets, etc, & I have never been disappointed! Those lovely silver dots work as well as an emergency (space) blanket, keeping me warm in cold temperatures. I used to swear by silk longjohns from another big "sports apparel" & gear, as well as leather from an HD store, & they were more expensive & didn't work as well for keeping warm even worn together. I bought a $200 North Face 3 system coat, & once I tried & wore a Columbia jacket, I gave that coat away. One day, I decided to blindly buy my daughter an Omni-Heat Omni-Tech coat for my daughter, we wear the same size, & I was hoping she wouldn't like it, but she LOVED it! That girl is so picky, she won't wear socks that "feel weird," & she kept taking my fleece tops & leaving them at school. Sher refused to wear a real coat, just pullover fleece & sweatshirts, until she got that's coat. One Christmas, I gave her almost everything Columbia, she went nuts when she opened this up! She got so giddy, yelling "SCORE! OMNI-HEAT! THANK YOU SO MUCH!," I was shocked at her reaction! She works at a hotel/resort chain at the oceanfront, & she was getting cold not only walking from her truck to the hotel, but inside as well, every time the doors open until she got this. She was able to wear it under her uniform, which made it that nuch better! Unfortunately for me, she wanted to keep it all, but I went & got my own. The only possible problem we had was when fully zipped, the neck was a tad tight I usually buy a Medium in tops everywhere else, because the XS & S arms & legs end up being too short, especially after washing & even line drying every item, cotton or not, & they eventually end up shrinking in the length, not the width. For reference, I'm 5'4" tall, 95 lbs, 32B,& small framed bone-wise. For pants, I have to get a 0 , 1 (or 24-26 in some stores that uses the European sizing), or XS,with regular to long length. I'm very disproportionate, because the inseam I usually get is the 32" so I'm not wearing pants & shirts too short. I'm short-waisted with long arms & legs. I love the fact that Columbia makes their long sleeve shirts, jackets, & pants long enough where I can buy my true size so it's not baggy everywhere else! There are some things I still buy in a Medium, because since I live close to the oceanfront, I still like to layer for the change from outside to inside. Almost everything I wear with Omni-Heat, I wear lighter weight clothes under it (& I'm hoping my thyroid will give me a break & let me gain some weight back). Columbia clothing usually runs on the small side, but both Mediums & Smalls fit me well, the arms/legs are long enough, & the price is right! You can't go wrong trying to keep warm with Omni-Heat!

Rated 5 out of 5 by from Love it! Does it's job great to hold in heat. I've only worn it in temps of 50-60 degrees but for me, it kept me warm.

Rated 3 out of 5 by from Runs very very small I really like this shirt but am going to have to give this away as it runs very very small. It's a nice shirt but order a size or two up.
Date published: 2016-12-07
Rated 4 out of 5 by from Too small I am usually a medium with Columbia and this was too small. Might want to size up if you don't want this shirt sticking to you like a second skin or plan on wearing something other than a sports bra underneath.

Rated 5 out of 5 by from Love it! Will be a great layer on the slopes and/or casual wear.

Rated 5 out of 5 by from my.favorite.shirt. I am a cold girl and this shirt keeps me warm without being thick. Hangs nicely - has a good weight. Bought a medium; fits my long arms and torso perfectly. I immediately wanted to get online and buy another, but haven't had the time. Buy this shirt.
