A little expensive for what you're getting Does the job - but it's not worth twenty bucks. I'd feel better if I paid 10 for this. April 10, 2014
Works Well I have two of these and they work well keeping my helmet clean. March 24, 2014
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. October 28, 2013
Enjoy the ride keep the sweat off A comfortable ride, your mind is on the road not on the discomfort. Keeps your mind on the road! Texture of the material doesn't pull on your hair, like wool. Non static . Great shape under the hood (helmet). Ken September 21, 2013
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. August 12, 2013
Does what it's supposed to do... does it well. Great ventilation, excellent sweat sucker. Bad sizing - I was expecting a "head-hugging" stretchable material but was disappointed that it wasn't. July 8, 2013
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. July 3, 2013
Good value Thin, light, great ventilation. Helps keep your helmet liner a little cleaner as well. June 18, 2013

A shopper asked: 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?

WingRider: THX,

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.

Geographer01: A head size of XS-SM might work for this helmet liner. However, I found it does not reduce helmet hair as well as another brand that has a satin liner. Sadly, I can't find the slik version I've worn for years with great satisfaction. Apr 10, 2012

Chris K: These Ventilator Caps are one size fits all. They are stretchy enough to fit larger sizes, but elastic enough to fit smaller as well. Apr 4, 2011
