Review summary
0 XL is a running sunglasses (Prizm (interchangeable) lens). Larger-face Prizm wrap (~26 g) with interchangeable lenses — choose when Radar EV Path feels narrow; still a daily/road performer more than a trail photochromic tool. I'd shortlist it for xL coverage for larger faces without jumping to Sutro bulk.
The trade-off is can feel wide on smaller heads — Oakley Radar EV Path is the cleaner compare when that is most of your week. It fits buyers who actually need a running sunglasses (Prizm (interchangeable) lens), not a one-product rotation.
