Hey guys, This year I've commuted with the bike through winter. It's all good, but I find it a pain to have to pack and unpack and repack my wet weather gear into my backpack every other day. I'm looking for lockable hard luggage that fits on or behind the pillion seat. I know I can get a tailpack or such but that would have to be taken with me when I arrive at the destination. Ideally I'd like to get something large enough to fit rolled up overpants and jacket and a small first aid kit. Any suggestions? Thanks all, Mr D.
