Zega Mundo and Mosko Moto
I have the Zega Mundo cases and they are great. I think they are the least expensive of the Zega line. Absolutely waterproof. I also use the Mosko Moto extra large duffle and it is top notch. It has an inner liner that is totally waterproof. Now as to crashworthiness...I haven't wrecked yet but when I do the damage will be my fault and I'll fix it as best I can. As for the storage and weather resistance, which is what I think luggage is made for, you can't go wrong with either the Zega or Mosko Moto lines.
