I like the idea of non-cycling gear for touring, since your spending so much time off the bike and need clothing to be multi purpose. It also depends on time of year. I personally like Wool 1/2 zip sweater, windproof vest and lightweight water proof hiking/climbing jacket.
The bike specific stuff while great on the bike, a) limits your (affordable) options a bit and b) wonky fit while off the bike hanging out around camp/hiking. I find a good fitting jacket with hood a do-all camp/riding jacket.
