Comfortable, cool, good cushion, more protection for toes riding a moto than the usual flip-flops. Everything else to minimum.
In addition to camera and 3 lenses, I have a Gigavue 40-gig hard drive for photo storage while on the road. It worked great.
Luggage: I started out with these:
I've replaced the Ultralite with an REI pack that has a light frame and several compartment separations, padded shoulder and hip straps. and will hold its shape when loaded unlike the Ultralite. The Rick Steves bag is lightweight and great if you're going to roll up your day pack and unpack it when you arrive. But I ended up wearing the day pack every day of the trip, everywhere I went. I got into lugging the big camera (I also have a pocket digital camera) with me at all times, and once the Gigavue had hundreds of pics stored on it, carried that as well, not taking any chances on losing stored files. I got a Jansport day pack with a little more body, padding, and especially compartments for pens, etc. Much better set up. Live 'n learn.
