Very good underhelmet cap, protects from wind as claimed.
Maybe a bit too warm on temperatures over 15°C, but I don't find it a big problem.Cap has reflection parts front and behind so you are better visible in the dark.
Two thing that did bother me are (and the reason for only 4 stars):
1.) Stitches on the front part of the cap. When used with a helmet that is a bit fast tighten the cap leaves two stripes on your forehead, so it could be solved better?
2.) Ear cover part maybe could be a bit bigger or maybe solved better, because when used with glasses sometimes it slips from ears or leaves ears uncovered when you put glasses on, so you have to fit cap again over your ears.
Besides this remarks I'm mainly pleased with the purchase
