Rapha, arguably the finest cycling-related clothing maker, has released their long sleeve shirt. It’s in two options in gingham and sports a tiny pocket on the back hem, a la bicycle jerseys.
M.L.G recently got ahold of one, and while the fit was way off (Rapha is hard to find in person in the US unless you live in Portland, NYC, or a few other places), the panel construction and detailing is amazing. If you’re of a narrow build and appreciate a nice shirt for spring, go for it. $130.
