I'm in between a medium and a large for tops and bottoms so I ordered a large based on the other review. Wrong move. This jersey is BAGGY which I noticed from the picture AFTER having tried it on. If you like some room in your clothes, then this will be for you. Sizing is true, just baggy.
If you're looking for something more form fitting, then don't get this.
The material is nice and considering how baggy the sleeves are, you'll need the thumb holes to keep the sleeves from rolling up as you ride.
Gave it 3 stars as it's not a bad, but definitely not for your typical road riding.
