Giro
SPF30 UltraLight Skull Cap

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.

If you're bald like me then this is a must have. The band is a little thick but it does the trick.

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.

Works as a sweatband and to prevent tiger stripes on the top of my head this lightweight, summer skull cap is an essential addition to my cycling kit

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.

I love this skullcap - it fits better and is more substantial than some of them other brands I�ve used. Definitely a Giro skullcap fan!

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.

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.

Works great. Don't notice it is there. I prefer the version with the brim as it is also good against glare but otherwise this model is fine.

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.

Helmet sits more comfortably with a light cap, also keeps the bugs off my scalp.

Keeps the sun and bugs off of you knoggen. Does OK with sweat.

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.

Great fit, works as advertised, a little too warm on warm days.

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.

Awsome
