Bigger guy, sweats a lot. Have used all variety of jerseys over 25 years mtn biking. For me, the Catalyst is great for breathability, comfort, fit, usability (love those snaps) and so far durability. I've mudded it up a couple times and sumple machine wash has been fine for getting right back to like new. Very happy, will buy again.
My son loves it!!! Excellent fit. Hes 9 years old, 4’ 7” and 74lbs, and the YL fits excellent - flowy and cool with some room to grow. He’s typically a size large at Old Navy and Target, for reference.
