Review summary
Rudy Project Cutline is a running sunglasses (RP Optics / ImpactX photochromic options lens). Race shield (~34 g) with quick-swap lenses and adjustable nose/temples — shortlist for bright road racing; ImpactX photochromic lenses are a known path when mixed light matters. I'd shortlist it for button-style lens interchange with optional ImpactX photochromics.
The trade-off is heavier than Kato / Phantom Air class — 100% S3 is the cleaner compare when that is most of your week. It fits buyers who actually need a running sunglasses (RP Optics / ImpactX photochromic options lens), not a one-product rotation.
