Columbia Total Zero Tank Top

Great fit and excellent for the hot runs.

It's a great tank - great look, feel, cut, fit. Not sure whether the cooling donut things worked, but it's a tank top so not overly necessary.

OK tank top but nothing more. Does not really have a cooling effect. I am a runner and I tried it on different occasions but came to a conclusion that it is just a tank top.

Material feels soft and light. Haven't used it on a hot summer day yet, but I expect it to hold up since the material seems to cool my skin down when I work out. The fit is good on the torso, length is good too - but the arm holes are huge. I wear a sports bra underneath and it shows on the armpit area. I guess if your chest is bigger this would work better. I am a 34B, 115 lbs and I ordered the XS.

I love this product as it does not trap heat. Even though other shirts does have breathability, this one actually feels like the heat you create while exercising is not kept close to you. If you don't like to just go out with a sports bra and you want to wear a shirt in the heat to exercise, this is the one for you. May even help mentally with your performance as you don't feel the heat.

Columbia has the best fitness tops in material and comfort. Although top fits somewhat small for me i'm keeping it. i plan on wearing this under other tank tops….or if i ever lose weight..i'll wear alone. Every time i buy a fitness top ..i hope it will be large enough for a big chested woman but still have its cooling properties. This top will be my first layer for sure. then i'll put a tank on top for my daily walks. this material should keep me cool and comfortable on those Summer walks or any activity where i want to feel comfortable in the summer.

I bought this shirt for my wife who is a runner, and she absolutely loves it. Says it really does help cool her down.

Medium on me (size 8) was skin tight, so I would suggest ordering up a size. If you look at the tank top on the model, it doesn't fit skin tight across the abdomen; so I would suggest ordering up. I actually ordered a size L in a different color of this tank, and it fit much better.
