CastelliOmbra Cycling Cap(Return to Product Page)

I have a reasonably large head and this cap is slightly too tight, but overall it's a solid product, looks good, and keeps sweat out of my face.

Excellent summer cap, incredible wicking and cooling ability and even helps a bit during rain. Not sure how it will fare in winter with wind protection, but it's not really designed for that use case. Very comfortable and stretchy. Would recommend.
