Merino Winter Cap
Reliable head protection from cold and wind in early autumn to mid-spring that fits well under a helmet.
Merino cap with thermocool fiber with the function of removing excess moisture and heat. The cap has an extra perforated synthetic lining on the inside for increased thermal comfort on the coldest days. It features a windproof membrane on its front part and on the visor to protect exposed zones. The cap can be worn with or without the ears covered, depending on the temperature and conditions. Thanks to its snug fit, it doesn't pinch under the helmet and is lightweight enough to be easily packed away in a back pocket if it gets warm.

Alpha Surprise!
The cap is lined with a very light fleece so warm and breathes well. The elastic tucks under my earlobes when others fall short. This can disturb my Airpods but they are contained and reduce the wind noise in them. I love the wind resistant panel down to 20F at least. Purple is so hip right now!Show full review -

Super czapka
Używam tej czapki przy 2 stopniach Celsjusza. Super komfort, brak odczucia zimna w rejonie zatok czy uszu. Polecam każdemu, kto ma tak słabiuśkie zatoki jak ja ;)Show full review -

Practical and quality winter cap
As it's one size only, my head is probably no the right size and I'd prefer the cap to be a bit deeper to fully cover my ears.Show full review -

Keeps warm but ears are not fully covered
I wore the cap several hours at temperatures from 10 to 0 degrees Celsius. Kept my head warm and was very comfortable to wear. The only thing is, that the ear flaps are too small, so they won‘t cover your ears completely. A nice feature is, that you can flip the ear flaps up if you don‘t need them. Works pretty well and the helmet fits without pressure.Show full review -

Excellent winter cap.
I really like that their is a liner inside the main cap giving extra breathability and warmth. Overall I rate this cap. Like others have said its a tad short on the ears but not a major problem at all. One size fits all. I wear a M helmet and found it fine but might be a bit snug on a larger bonce.Show full review -

good quality
I've not tried this in the cold yet but it fit's snugly under my crash helmet and feels very comfortable. Based on my other Isadore kit, I have no concerns on this doing what it is meant to do!Show full review -

It`s very comfortable and warm. I love no bland name on the sun visor. I have never worn Merino cap. I recommend it in winter.Show full review -

My Best winter cap
Perfect compromise for winter conditions - cold air protection of front part of the haed and no overheating of the rest. I use it for MTB under my helmet. I will by once more for possibility of change during my trips...I tryed lot of caps, but this is realy the best compromise. I love it.Show full review -

Material and style good, ears not covered
My only grunt is that my ears are not fully covered with the flaps. They should be larger for normal head-sized people. No complaint other than that.Show full review
