I have several Pearl Izumi jersey's and ALWAYS wear a medium so that is what I ordered. Way too baggy and the sleeves go beyond my fingertips, at least 3" too long. Returning for a small and hope that fits! Also returning my girlfriends jersey that is way too small. PI sizing is not consistent!
The fit is a big surprise. It actually fits a normal person . I am not a pro racer and I appreciate the sizing. The sun protection is good and the jersey is cool and comfortable. I bought two and will buy again when the time comes.
I use this jersey every time I ride when the temperature is about 62 F because I do not like to apply sunscreen. The color is perfect to enhance my visibility. The jersey is larger than expected. I normally wear an XL, but it was too large. The L fits perfectly.
