The 37 Giordana Sport short-sleeve jersey ($ 190, unoimports.com) is nicely retro. The merino wool used in the jersey is cycling’s first high-performance fabric, able to wick away moisture to keep you cool, while also able to trap warm air when the temperature is brisk. Polyester bolsters the shape of the garment. The 38 Sportful Super Total Comfort bib shorts ($ 310, mvc46.eu) are totally modern. The panels are woven, not knit, which means your muscles are better supported. Silicon dots make up the gripper at the end of each leg. There’s also an integrated cellphone pocket.
