Totally worth it
When my beloved pair of Castelli bibs blew a seam on a ride (luckily I noticed it when I got home and didn't have to deal with the knowledge that I was riding home with a slash of my butt cheek exposed) I decided to give the FRC bibs a try and splurged on the matching jersey. I have been more than pleasantly surprised. Even straight out of the packaging I was impressed with the workmanship and quality of the material. The jersey is ridiculously comfortable with a close fit but doesn't make me feel like a human sausage. The material feels and works great while looking sharp as well. At half price, it's a bargain to get a matching, quality kit.
Note: I have the Black/White Arco and the white is pretty transparent although it is placed appropriately. I don't have any crazy patterned sports bras or tattoos, but if I did, you would definitely be able to see them.
