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!!

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.

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.

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.
