Spatz Shield sunglasses review: The best photochromic cycling glasses

I’ve tried more or less all the best cycling glasses on the market at this point. Winter is obviously a bit of a downtime for cycling glasses testing, and I tend to just chuck a set of clear lenses into something and go from there. The 100% S3 is usually my go-to, but recently I’ve been testing the Shield from Spatz and it’s certainly given more food for thought for winter testing.

The Shield is Spatz’s first foray into the world of cycling glasses, and the brand half-arsed it. They are massive and sturdy, but unlike most premium glasses that usually either come with just a clear lens or no spare at all, these come with a photochromic option to supplement the main sun lens.
