Giro Ambient Skull Cap

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 bought this hat for winter cycling to increase my everyday wardrobe from two hats to THREE HATS. I am a huge fan of the cycling caps with bills so I was glad to find this one that had both long warm ear covers, and shading/shielding bill features, since my two at the time were just skull caps.

It is toasty, has long side flaps to keep your ears warm, and also has a nice little forehead flap that keeps your forehead warm. This forehead flap has been very useful in this time of constant temperature checks when I walk in to work with a frozen face. My other hats cause me to fail checks with a "low body temperature" reading, but wearing this hat has been keeping my body temperature "normal." With that being said it is obviously not as breathable as my other thin skull caps, but that's kind of the point.

Also great that it is made from polyester, polyurethane, and nylon...NO WOOL, making it a vegan option!

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.

Used to wear headbands and (ski)helmet liners until I found this one. Fits perfectly under the helmet and is warm and windproof (tested on rides into the mid 20s). The small brim is a great additional feature.

This is a great product, exactly what I expected, the service and ease of doing business with BikeTiresDirect makes the purchase that much more pleasant. Thanks!!

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.

This cap has been great in the cold, but I wouldn't recommend it at temperatures below 35deg. Also doesn't work well with Aftershokz headphones.

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.

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

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!!

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.

When it's cold enough to cover your ears and get some thermal insulation for the head, as well as provide some protection from rain, this is a hat that checks all the boxes.

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
