Whats with all the hype around Castelli and Rapha thermal jerseys? Are they really worth the hefty price tag or are you just paying for the brand name? Ive seen some great reviews of jerseys from lesser-known brands like Cafe du Cycliste and Velocio that seem to offer similar performance at a fraction of the cost. Can anyone whos actually worn these jerseys in the cold, wet conditions of winter tell me if the premium brands are truly worth the extra cash? Or are you just drinking the Kool-Aid and buying into the hype? Lets get real here, folks. If Im going to spend over $200 on a jersey, I want to know its going to perform better than something half the price. So, which thermal jerseys are actually worth the investment for layering in winter?
