When do you wear your hacking jacket?

[FunkyFilly28]

As above, really. I've got a Pony Club test during half term and I'm supposed to wear a hacking jacket. I have a navy show jacket that I use for SJ and Dressage but I don't hunt. So is it worth buying one if I may wear it again in the future?

Pics of you in your hacking jackets and where you got them from would be much appreciated too!

Thanks
