I admit I had high hopes for this shirt, its got such a great design, I wish the full-color skull was on the front too. The fabric is so lightweight! Its the perfect wicking fabric, you barely know its there. Why almost perfect? Sizing. I'm 6'2" and 175lbs, slim build, and I wear XL in all my Cycology gear (short sleeve jerseys, long sleeve base layers and cotton t-shirts) and everything fits perfectly. With that in mind, I ordered an XL for this shirt and its too big. I can't decide if this shirt runs big or if all the other gear that I mentioned runs small, I think its a little bit of both. My advice is that you order one size smaller than what you normally wear in Cycology gear for the right fit. I admit, I'd return it and get a smaller size but having to pay for return shipping is a real bummer. Bottom line is that if you get the sizing right (this is a generously cut shirt) you will love working out in a very comfortable workout shirt.
