Jackets to wear while riding out is really down to personal preference in terms of style, waterproof and windproof, really go without saying for your comfort, and as mentioned hi-viz is the sensible option - although if you're after a versatile riding jacket a good hi-viz vest and other accessories is a good compramise, otherwise you'll end up spending a fortune and filling the coat rack (I speak from experience!). The 2 real options of windproof/waterproof jackets are blouson style jackets, and longer fitting jackets (perhaps google Dublin Blouson, and Dublin Empress to show you the varying styles), obviously other brands such as Mark Todd, Toggi, and particularly Mountain Horse also have a great range of riding jackets. For a more novice rider Mountain Horse do the Body Guard Jacket which offers a little more protection!!

But if you're not looking to spend this much, both Dublin and Saxon offer some really great value for money jackets
