I'm mostly bald and I tend to run hot. Head coverings usually heat me up more. The Giro cap has been great. It sits above the ears and doesn't heat me up. It allows me to not put sunscreen on the top of my head, so it can't drip into my eyes. I'm glad I bought it.
I just ordered a second Giro Skull Cap because I was so happy with the one that I used last season. I have tried many different manufacturers skull caps and usually either the fit is tight, or the material used doesn't soak up the perspiration. The material GIRO uses light weight yet durable and the headband is very comfortable. I would recommend this who has been dissatisfied with other skull caps.
Its a bit too big for my 21 12 inch head but I like that it still fits above not over my ears so it's more to my liking for a cap under my helmet. It absorbs sweat so it works well in hot or cooler weather.
Bald head approved. Good value if purchased on sale. This works as well as the summer weight skull cap from PI, though this one might be just smidge thicker. Washes up well in the washing machine. I always line dry these, so no idea if they'll shrink in the dryer.
I've tried a lot of these. This one, the only name brand, was very small and heavier than the rest. SPEG is the best so far.
Like the material however the band is only 11/16 of an inch wide, With a medium size head the one size fits all is a bit tight, Perhaps it will loosen up.
Living in Hawaii, I do most of my riding in hot and humid weather. The ultraLight skull cap helps keep the sun off my bald head and delays sweat from dripping in eyes. It's a bit expensive for what it does, but it is comfortable. Just don't forget to wear your helmet with it. I've left the house with just the feel of the cap on my head, thinking it was the helmet.
This cap is great when I'm doing a longer ride on a hot, sunny day and don't care to get a sunburn through the vents of my helmet. It's light enough to not be too hot and does the job of preventing my scalp from getting burned.
Fits easily under the helmet. Hardly know I am wearing it but I feel reassured I am protecting my bald pate. Love that it saves me from applying sun block to my head and waiting for the eventual sting as perspiration and gets into my eyes.
Fits well especially on bald head. Comfortable. Contained sweat up to when nothing will. Bought a second one for that purpose.
Does what it's designed to do well, wick away sweat, provide protection from the sun. I like the Pearl Izumi (discontinued) skullcap a bit better...higher SPF, nicer fabric, etc.
