GiroSPF30 UltraLight Cap(Return to Product Page)

Great fit not too tight, blocks sweat and fits well under my helmet. Better than the last 3 caps I have tried

A little spendy for a cap, but it is super lightweight and provides just what I wanted - a cap that didn't feel like it provided any insulation value but did provide a visor for those early morning or late evening rides with the sun low in the sky. Visor just big enough to keep the sun from shining between forehead and top of sunglasses.

I looked in vain for a cycling cap with a place for a woman's ponytail but I cut one in this cap and stitched around it to prevent raveling. It works and I'm happy with the results. This cap is thin and easy to wash.

I have looked for a hat like this for a long time. This is the first one that fits the bill! Just enough of a cap to do the job. I cut a hole for my ponytail and the cap stays in place perfectly. Love it!

One of my favorite caps. Traditional cotton caps were always uncomfortable to me when worn under helmet. This ones great-thin fabric and mesh takes up no room under helmet and breathes well, soft fabric feels good against forehead with no crinkled edges, smaller bill doesn't creep down or get in the way when in the drops. I wear this in spring/summer mornings when it looks like it may rain.

I use this on the hottest rides. It's not the toughest hat you'll own (mesh) but it is most certainly the lightest and most breathable.

Get one and get it on sale.

First time I wore a hat with visor as opposed to a skull cap. Visor obstructs vision and forces you to lift your head a little higher

I wear a cap under my helmet on every ride year round. It protects my bald beak from the sun. Also learned my lesson a few years back before I started wearing a cap when I got stung by a bee on the crown of my head on a very steep and fast descent off a mountain climb. Anyway, this cap is super light and breathable. You can easily tilt the brim when you need to without interfering with your helmet fit. The material wicks away sweat unlike the cotton caps. The SPF is a bonus. I look to buy a couple more to keep in my cap arsenal. If you want a cap under your helmet this one is the best I've had so far...and you should see my collection.

This is the first cap I have used for cycling. I wanted something to provide additional sun protection with sunglasses. Love it. Snug fit doesn't affect my helmet. Keeps sweat out of my eyes and great sun protection. Plus I stay cool.

Hands down the best summertime cap.

Ultra lightweight and nearly impossible to feel under the helmet.

Giro really made a great product here. Fits perfectly under my Aeon.

I totally recommend this cap for summertime use.

Cheap enough here to get a couple.

Works perfectly. Like the copy states great for hot summer rides but even in cold, keeps sum out of eyes and stops sunburn through my hair on top of head (through helmet holes).

The cap is okay. Biggest issue are the seams are large so they sometimes and become irritating on a long ride

I wanted a lightweight cap to wear under helmet to keep the sun off my head. This one is perfect!

I wanted a simple cycling hat to help minimize sweat from pouring into my eyes on hot days as well as to provide a little throwback cycling hat style when taking off my helmet at rest stops. This one does the trick. I have worn it on several century rides and found it holds up well and doesn't cause my head to overheat. It is very thin so I have chosen to wash it carefully by hand between rides verses running it through a machine. It drys quickly and has continued to look new.

Great fit, bill doesnt block my vision at all, and it stays cool. Just wish it had more colors.

Love this. Protects my enlarging bald spot from the sun, keeps the sweat out of my eyes, and I don't notice it's there. Also useful for glare. A total winner.

This hat is perfect for rides where a bit of visor coverage is needed. The black color under the bill is much better than white. Love this cap!

I really like this cap. It fits my head well and looks good. I wore it out on a very rainy day and hung it to dry at home. I may have bunched it up, I don't remember, but the bill is a little wrinkled. Not a big deal at all. Just a heads-up. I'm still giving it five stars.
