What Our Gearhead(R) Experts Are Saying: "I use this under aero and lightweight jerseys when it's hot or the pace is high. It pulls sweat off the skin fast, never bunches, and the bonded seams stay invisible even on long rides. It's one of those pieces you forget you're wearing-in the best way." We rely on the Pro Team Sleeveless Race Baselayer when conditions demand precise temperature control and zero distractions. Rapha designed this base layer for hard efforts and long days, where managing sweat and heat can make or break a ride. From sustained climbs to full-gas intervals, it keeps our core dry and comfortable so we can stay focused on the road ahead. The lightweight fabric wicks moisture efficiently while regulating temperature across changing intensities. Stretch side panels move naturally with the body, and bonded seams reduce bulk and friction under close-fitting jerseys. Finished with subtle graphics inspired by cycling's history, this baselayer blends modern performance with a nod to the sport's roots.
