礫石車帽

The brim is stiff enough to actually keep sun and dust out of my eyes on loose descents, which I didn't expect from something this light. It stays put under a helmet too, no bunching at the back. Genuinely my go-to now for any ride that leaves the pavement.

Wore this on a 40km mixed gravel loop and it never shifted under my helmet. The cotton feel is light enough for summer but the brim still flips down when the sun's low.

The brim actually stays put when I'm bouncing over washboard gravel, which is more than I can say for my old cap. It's breathable enough that I forget I'm wearing it on long exposed stretches.
