We bought saddle bags for our motorbike off a small street near Hang Bong - my memory is hazy but on a map (which I am terrible at reading) it looks like it was Ha Trung. This street sold lots of leather goods, seats, saddle bags, jackets. Our bags were reasonably priced (time has eaten away exactly how much), but it was certainly strong and durable, and generally waterproof. If you're doing heaps of riding, it might be a goer for you as well mate.

yep! exactly! you can order or tell them what you want in Ha Trung. They make leather bag and the bag like in army!
