Cool and Comfortable! Genuine Do Wraps Sweatvac Ventilator Cap fits my head well and the seamless design doesn't create any pressure points when I put my helmet on. Cool and Comfortable. August 26, 2014
Took all my sweat I used it on a 3 day trip and it helped a lot by taking my sweat. Will buy another one if I am going for a much longer trip. June 11, 2014
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. May 27, 2014
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. May 26, 2014
Great Little Gear I have oily head and tend to sweat a bit while wearing my helmet. This little piece of gear mitigate both oil and sweat from ruining my helmet. It does reduce the smell so I don't have to wash the comfort liners that often. It is very light which makes it a wear and forget gear. Additionally, it does keep my head warm in winter/wet season. Though overpriced for what it is, I like it to the point I purchased two of them so I can wear it everyday while commuting. May 24, 2014
Nice cap This cap fits good and is not bulky under my helmet. It helps keep my head cool with the wicking materials. May 19, 2014

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

Kevin R: 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. May 22, 2014

Allen C: I think it depends on your head shape but generally I don't think it will cover ears. It doesn't cover my ears unless I pull them down hard over my ears but eventually they'll retract back up. Jun 11, 2014
