Castelli Radiation jacket review

Cycling Weekly Verdict

Performance-wise, there are numerous reasons to love the Castelli Radiation; it does a good job of justifying its cost because it does so much for your cash. One little patch of ice could wreck it, however, so the price is a little hard to justify.

Like Assos’s Fugu jacket, the Castelli Radiation is designed for the coldest winter conditions.

But unlike others it has three layers and various parts that can be unzipped. As always, fit is an important starting point and Castelli has wisely opted for a long sleeve, but a medium that fits six footers is just silly, so check the sizing.
