Review (3/5): be aware no holes in the cap!
I had some similar caps in the past and really likes the chin attachment on this one to keep the cap in place .I have a small head and wear small helmet but this cap is so tight ! I can't barely fit it on my head and although it is stretchable rubber , I quickly got a headache! there are NO holes , you have to pock them yourself with the plastic tool included, which broke within the first 10 minutes !
