Polypropylene clothes

I like polypropylene clothes for their practicality, their warmth and their weight but all the items I have even seen all are designed with a practical use in mind - as hiking gear etc.

Are there any designs out there which would look good when worn for a night out? By night out I am not talking anything posh/upmarket but in a average restaurant, cinema, city centre pub etc?
