Review summary
HiPER race shield with simple lens swaps — strong bright-sun road tool under Kato money; not the first pick for photochromic trail ultras. Here's a practical take on the 100% S3 — what it's for, who it suits, and when to pick something else. I'd shortlist it if you want race-shield coverage at a sharper price than Oakley Kato, spare clear/low-light lens common in kits or secure sport fit for hard road efforts. Skip it if lens swaps leave fingerprints more easily than MAG systems or less trail-photochromic versatile than Julbo Reactiv wraps is most of your week. 100% S3 is a running sunglasses (HiPER (interchangeable) lens).
