awesome cap

I've used it several times
True to size

I have a large, bald head, and I always wear coverings under my helmet to avoid sunburn, to avoid creases and indentations, and to wick sweat away from my helmet, thereby extending the lifespan of the lining. Plus it's great to wear when I stop for coffee. Most of these hats are either cotton (which makes no sense if you sweat), or they're too small. The A/C cap is perfect - it's stretchy and fits, it looks great, it wicks sweat off my head and out of my eyes, and although it isn't as cool looking as the retro cap. - which is cotton for some reason - the scorpion logo is actually a nice plastic applique which gives it an expensive look - and the flip side of the bill, which you don't see in the pictures, sports a cool sewn-on patch that says "rosso corsa". Love it.

Fits the Bill

I've used it several times

Well made and comfortable. Fine mesh makes it perfect for avoiding forehead burn without having sunscreen cascading into your eyes on hot days.

Looks good, good fit under helmet

I've used it once or twice and have initial impressions
True to size

This is a bit thicker across the top of the head than some other caps, but it isnt uncomfortable at all. I wear a L or XL helmet and this sits nice and close to the ears so t doesn’t interfere with the helmet adjustment band. Good construction.
