In reply to Mr Ed:
I totally agree with what you say. I have the Essence jacket and the only thing that lets it down is the hood/visor arrangement. It's pants. The only way that I've found round this is to wear a peaked cap(Innov8 running one) but downside is you can get too hot if running with hood up and cap on.
I guess that a wired peak would limit the size that you can pack the jacket down to though so maybe that's why they don't use them on superlightweight jackets.
