Fox Racing Men's Flexair SS Mountain Bike Jersey - Breathable Short Sleeve Cycling Shirt for Mountain Biking & Trail Riding - Lightweight & Moisture Wicking Performance Top

I bought this to match the aesthetic and theme of my road bike. There were a lot of reviews discussing the sizing of the jersey. I initially bought the XL since it appeared that the sizing was really small based on reviews. However, the XL was an XL, but had a fit I would have expected for a jersey like this. It fit, but was still big on me. I'm 5'-10", 158 lbs. I returned it for a M, which is what I wear normally. The fit is more form fitting than a t-shirt, but the length and shoulder seams appear to be in the right spot. So, the M was right for me. It's a bike jersey. They run fairly tight so I can see how it might give the feel of being too small. If you want something a little looser, I would go a size up from your normal.
