I'm not sure why but when the design came out it took me a while to realize that the logo is actually a U and an A put together. The company itself began in 1996, and provides a wide array of clothing and accessories, usually used for sports. The logo is made of a custom typeface.  The emblem and the font are both nice and work well together, but I'm not sure that such a large emblem should be sitting on top of a much smaller font.  The designer probably could have found a different way to position the font.  Other than this the logo looks very nice.
