First off, just to say, I wouldn't spend $200 on a jersey, but with Real Cyclist's great deal I was able to buy this jersey at significant savings. It's definitely a couple of notches above the standard jerseys that run $65-90. Great materials and comfort....all the other previous reviews go much further into those aspects. Everybody wants to know about fit....I am 5'8" 146 lbs, 30.5" waist, 38" chest....went for the Medium, per the lower end of the Capo (medium) chart range. It fits that way....snug at the waist, close fit at the chest, which is fine. I didn't want the jersey to fit too tight, as I don't come anywhere close to racing. It fits similarly to my Pearl Izumi mediums and my Castelli large GPM jersey.
The sleeves are longer than normal, which is ok, but the black armbands make the white/black jersey look a little "formal". I ended up folding the sleeves up (2 times the width of the black band) and it looks nicer, IMO, with mostly white showing. Rode in 90F degree weather and it performed admirably; fast drying.
Happy with the buy :-)
