Giro Ambient Skull Cap

Protects from wind, can cover ears, fits comfortably under helmet. Great winter hat!

It is a great skull cap for cold weather riding. It fits perfectly under my Giro helmet, and is very comfortable. The ear protection is much better than my other skull caps. I use my sunglasses with this cap, and have no complaints with the glasses falling or getting away.

There is some wind noise, but not as much as my other caps with the ear flaps down. When the ride warms up,

the ear flaps go up and it works as a wonderful temperature control.

I wish I had these sooner!!

I have tried all sorts of head coverings under my helmet. Not only does this skull cap fit comfortably under my helmet, but it keeps my ears warm...most important!!

I bought this cap for 20-50 degree (F) road bike riding and training. The short bill is excellent to help keep the rain from dripping off the helmet into the eyes and the wind stop frontal section is just what you need to make the cold bearable at speed.

My head size is approximately 6 5/8 (small) and the fit is nearly perfect. My only note is that the ear flaps tend to creep up very slightly. This is no problem since I wear a thin baklava over this cap on cold days and it holds the ear flaps in place. I would purchase this again as it it completely satisfies my search for cold weather protection, light weight, and fit. As mentioned above, I do wear a very thin baklava for added face and neck comfort on the colder days.

I use it under my helmet on coldchilly days. Fits perfect under my Giro Helmet and is not too hot when the day gets warmer and I get warmer. Have worn it comfortably enough up to almost 60 degrees, typically wear when below 50ish at start.

Having used the Giro merino winter cap for years,

I've given this a try, & it's working well.

Covers the ears, but you can uncover them on the fly for temperature control.

Not overly warm- I used a 2nd thin skull cap for a 40 ride, fits under helmet well.

Get the large size- tight fit cuts circulation.

The best part is the brim, which is enough to keep rain out of the eyes, but doesn't obstruct vision

when in a low position- a problem with many caps including the merino one.

used this cap in temps from 40's to the 50's. keeps your head warm. the ear flaps want to flip up when riding.

Good design,warm,wind proof front and breathable.

Needed a cap that was in between a thick wool cap and a cotton cap for winter rides and this cap fit the bill to a T. Great for temps from 32 to 45 but can get a little toasty above that. The fit is great with just enough ear coverage and the bill long enough to provide protection for glasses while still venting. Fits under my helmets just fine without bunching up or moving around. Great product especially for the price!

Wind proof great. Ear coverage great. There is nothing to dislike about this product. Material is great. Just got it rode about 5 rides in pretty cold temps. Love it. Great under my ski helment also.

I ride year round and wear some kind of hat under my helmets round. This is perfect for fall and spring rides. Fits perfect.

This cap is really good - I use it everyday on my winter commuting rides. I covers my ears and the small brim is good as well. It conforms well to my head and fits snug, but not too tight.

I had an initial concern that it would be either too bulky or not warm enough. Neither was the case. I am surprised at home warm it is for being so thin, but when the temperature drops below 15 F, I put a balaclava over it and I am still able to get my helmet on.

Good cap. Thin enough to fit under helmet but tight fit none the less-

Quite warm, simple useful cover...would recommend.

During winter had been using separate head band and hat. Head band would slide all over the place and not cover the ears really good. Decided to go for something better, Giro Ambient Skull Cap, Great hat, ended up buying an extra. When the weather turned wet, head remained dry. Can't wait for winter...

I am a weekend cyclist and this cap is a must in the Midwest since it does not get warm until mid June. This cap fits very well (I have the LXL) and works well with my helmet.

It fits great under my helmet and keeps my head and ears warm. Allows my head to breath as well.

Great

This cap is great in the winter. I does keep your head and ears warm but it does breath enough for your head not to become extremely hot.

This hat rocks. It was a replacement for a PI thermal hat that was out of stock. I love the the way the hat wicks away moisture and the brim keeps the rain off of my face. I rode 40 miles this past Sunday in a cold rain and my head stayed dry and warm. If only it could protect me from the spray off the wheel in front of me.
