Rated 2 out of 5 by 2 reviewers.
Rated 1 out of 5 by Ineffective cooling plan I bought this for my wife. She was not impressed. The salesman in the Columbia store in the airport showed me the cooling demo, I was totally hooked. My wife (dedicated half marathoner/ten-miler with a full marathon to her credit) wore it the first time in the fitness center on the treadmill. There was zero cooling effect. I said maybe because the air movement was too little. She said OK. She wore it outside in the Fort Bragg, NC heat of May/June. There was zero cooling noticed. Today she handed it to me out of the clean clothes pile and I saw a bunch of the little blue cooling dots had completely rubbed off/ washed off. Here I sit with no receipt and no way to fly back to Oregon, not to mention no cool present for my Mrs. June 28, 2014
Rated 3 out of 5 by Not feeling the cooling. I have to admit, I feel no cooling. I am slightly frustrated by this. It is a great shirt, and fits well and is made well, but "omni-freeze" seems to just be "omni-sweat". I have worn it for running in AZ, several runs in South FL and hiking in AZ now. Nada. No cold. Maybe my expectations were too high. The shirts is great, except for that. April 20, 2013
