Review on Ultimate Performance and Style: Columbia Rules Sleeve Dolphin Medium Men's Clothing by Chris Thrower

Bought the light gray version, nice colour. not too dark or light. Technically, this is my first time buying a shirt with Columbia's OMNI-FREEZE technology, which is designed to keep you cool when you sweat. I didn't feel cool. In fact, the fabric makes the shirt stuffy. If this shirt wasn't so loose, making it feel more airy, I would probably return it. Wouldn't buy again.
