Question: what are the Velcro straps for on the back of the cap?
Document: The velcro crackles constantly when moving. There are two loops on the top of the cap that I have no idea what they do. And the mask doesn't fit closely enough to my face beneath my eyes, so that when I breathe my glasses fog up.Note: I decided to ditch the cap part all together and replace it with a normal wool-blend knit hat.
It's also pretty thin. If you wear just the hat part the Velcro scratches the back of your head and neck. Its really tight around my nose but I have a bigger than average schnaze.
Winter in Chicago -20 degree winds on a bicycle in the windy city. 4.6 miles and this thing kicked ice. Kept me warm and it fits well under a Bern helmet. In fact its got little Velcro straps to hold onto a Bern Helmet.
I commute on my motorcycle year around. I removed the top cap and my full face helmet keeps the top of my head warm and the N-Ferno keeps my face and chin warm.If I didn't have this, I wouldn't be able to ride in the 9 degree temps.
not to snug not to loose, fits right and adjustable by velcro. The fleece is not cheap looking, highly recommended for the price.
The Velcro kinda cuts head, and I thought with the nose cut out it wouldn't fog my safety glasses up but it still does
This also seems to make the mask seal better. The velcro holds to the knit hat reasonably well as well. This, I think, still makes it worth what I paid for it.
This piece is pretty comfortable, breathes well and definitely keeps my head warm. The velcro strips allow the separation of the balaclava into a comfortable facewrap and hat. Both are fantastic on their own, but it's when they're as one piece that my main problem crops up.The velcro strips are hard, creating edges that rub and irritate the face, especially the ears.
if you wear around the chin, the velcro is a lil annoying. you can wear this as a beanie, neck warmer, full head, or on chin. the neck is covered good and it fits good overall. with goggles or glasses it keep you very warm. but not for extreme(below 0 and windy) weather. I live in PA and is good for my area. also works good for riding motorcycle.
I gave it 4 stars because a few minor things but overall i love it and works good. It is not windproof because of the vents. but keeps your face warm even with the wind blowing in. not much comes through vents. the vents do a good job and not much moisture produces inside at all. they have velcro on head. that is my main con. i do not know what they would be useful for. they are irritating to me and pointless.
Answer: yes
