With lots of options on fit, performance, added extras, and of course, the all-important look, your riding jersey needs to tick a lot of boxes to fight for your hard-earned cash. Renen keeps things simple with its Flow jersey, focusing on handcrafted construction and high-performance materials. It doesn’t hurt that it also looks good, so after a few months riding in it, I see how many boxes this jersey ticks and if it can measure up the best MTB jerseys out there.
