Fits the Bill

  • Familiarity: 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

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: 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.
