Kitletics Review · 8.4 Good

100% S3 is a running sunglasses (HiPER (interchangeable) lens). HiPER race shield with simple lens swaps — strong bright-sun road tool under Kato money; not the first pick for photochromic trail ultras. I'd shortlist it for race-shield coverage at a sharper price than Oakley Kato. The trade-off is lens swaps leave fingerprints more easily than MAG systems — Rudy Project Cutline is the cleaner compare when that is most of your week. It fits buyers who actually need a running sunglasses (HiPER (interchangeable) lens), not a one-product rotation.
