This post is duplicated on both Bikerader and CycleChat I wear Ventile a lot when outdoors and although being cotton is a wonderful material for cold dry environments. Ventile is advertised as being waterproof which is not strictly true although if you keep it proofed with nikwax or smaller it is quite waterproof. The main advantages of ventile is its windproof properties, breathability and bombproof ruggedness. I know there are a couple of companies that make ventile cycling products and many of the ventile clothing companies are unusual in that they are very accustomed to customizing a product to your needs for an extra few quid. I am thinking of getting a ventile jacket with customized pit zips and possibly a net lining. My question is do any of you use a ventile cycling top and is so what do you think of it and how does it perform. I know it will only be of real use during the colder months.
