I shave my dome completely bald now that I am in my late 50s, and it used to be that my hair would catch some of the sweat coming off the top of my head and prevent it from streaming down my face and into my eyes. No more: once my body temperature rises to a certain temperature on a ride, a point comes when I don't just start to "glow" - the sweat just pours off me, like a dam bursting. Well this cap is a brilliant solution. The wicking material stops the dome sweat, and the elasticized temple band sops up the sweat on it's way down to my eyes very efficiently. I don't need to spread sunscreen over my dome anymore, because the skull cap is SPF50! Last summer I had to stop and dab a rag every five miles because of the sweat pouring down, but this cap just lets me ride on a summer day. I need to get a couple more, actually.
Great fit in my opinion as it covers the hair but does not stick out beneath the edge of the helmet in the front. There is a little red tag on the top which makes it really easy to remove by just lifting on the tag.
I have several different skull caps that I regularly use since I ride practically every day. I like skull caps because thy reduce the stench on my helmet pads and straps. This particular one has a tighter weave but breathes very well even on warm days. I have not had an opportunity to wear it yet on really hot summer SoCal days. I have some very light skull caps and a thick winter like one with protection for the ears. This skull cap seems to fit in between from a temperature perspective. I plan to acquire a couple more now that I have tried it and like the fit and quality.
I use a skull cap in all conditions. For colder temps, I like a thermal cap. But for temps over 45, this is my go to cap. It keeps my head cool and covered from sun, and does an adequate job of soaking up sweat. I have two that I keep in rotation so I can wear one while the other is in the wash.
