Works well, not bulky
The cap works well to keep my helmet liner clean. The band is comfortable and very thin so it doesn't cause discomfort under the pads.

Best I've found
I've been trying different beanies to try to keep my helmet fresh longer. This is the best I've found so far. I like that it doesn't cover my ears, but does cover my forhead/hair/neck enough to keep my personal funk from transferring to my helmet.

Not worth the $
Terrycloth sweat band and mesh top = not worth $20. Would like it longer in the back and over the ears to cover the whole scalp area.

Best $20 I've spent at Revzilla!
I love this cap. It's super-cool and keeps my gnarly sweat off the inside of my Nolan N104. It's so breathable that I can't tell I've got it on, even in 100-degree, 60% humidity Missouri weather.

Good for your helmet
I live where it very hot and this helps keep the sweat from going all over my helmet; a definite must for anyone that rides in the summer.

I don't feel any cooler or less sweaty wearing it
I don't really feel any difference between wearing it and not, although it is summer right now and hot is going to be hot. Does seem to keep my helmet cleaner, especially after work when there is gel in my hair. I dont have any gel smell in the helmet so far so that's good. I originally bought this thing to help keep my helmet cleaner and so far its working. Would have gave it less on the "bang for the buck" but its been fine going through the wash a few times so its fairly durable, although i've only been using it a few weeks now. I wear a size Large helmet and this thing fits fine.

Much better than a do-rag
Good quality with a good fit to the head. The cap is a bit thicker around the ear band (colored part) than my previous caps which can be good or bad.

My helmet fits perfect without the cap and when I install it the helmet fits a little too snug. So this is good of your helmet is slightly loose, but bad if your helmet is more on the snug side.

I could not tell if I was cooler wearing the cap. I wear a Shoei RF1100 helmet which vents very well.

Colors are vibrant.

It fits too loose, not sure it stops sweat...
Been using it to keep my hair in place, it somewhat works, it doesn't fit snug, it is just sort of, there... Not a bad a product, but, certainly not an excellent one.

Worth Consideration
I am very happy with my ventilator cap. Extended stops at traffic lights, or when keeping my headgear on while buying fuel, etc., is when I best realize the advantages of this product.
August temperatures here have been north of 100 lately, and anything that keeps the ole noggin and yours truly comfortable is appreciated.

Keep helmet liner cleaner from hair lotions or gel that I may use and protect my hair styling as well. Also to absorb sweat on hot summer days

Because I live in a warm climate, I sweat, and want to minimize the effects on my helmet liner.

Due to the humid climate of Guam, sweat and gunk from hair gel can really funkafy a helmet. I was hoping that this product would reduce the number of times I would have to run helmet liners through the washer.

Bought a replacement one. This cap does well with head sweat. However, unless you wash it regularly, it will only last a season.
Sang L on May 27, 2014
I don't like the doo rag look or the tails hanging down. This is a much neater look.

I needed a sweat cap under my helmet for summer and some one commented this cap does not stick/static my hair.

Not sure how to make a wild guess on the size of these things. I need one to protect my hair under the helmet, and I wear an XS to SM. Could I get a guess on that?

A shopper on Apr 4, 2011

I thought the same thing until I got it. I don't think you will have any problem with this at all. It is very light and I thought it would actually be too small for my head. I wear a Medium helmet in most brands.

this is made well and I have to say that it could fit small med and probably large by the way the material is. I would definitely recommend you at least try it, besides the return policy and procedure for Revzilla is actually a pleasure to deal with. You don't have anything to lose, and I really like mine. I plan on getting the winter version along with another one (summer version). (one to wash / one to wear).

It is super comfortable and you don't even know you have it on. Stays in place too even when you are taking off your helmet.

Give it a try.
Will the stitching leave a painful mark on forehead after long/race use?
A C on Oct 4, 2016
BEST ANSWER: I've bought and worn so many different brands of this style headwrap, and all leave some degree of a mark after a couple of hours under my helmet. That being said, I find this one to be one of the better ones, at least in that regard. I do find it to be somewhat itchy, but running it under water prior to wearing it seems to help with that.
Would this cover my ear?
A shopper on May 22, 2014
BEST ANSWER: It covers the top half of my ears. I got this specifically to hold my ears close to my head when putting my helmet on. It is very thin, and the venting on top makes it very comfortable even in warm weather.
r they one sizes fits all?
