had a huge backpack style (and smaller clear ones) go all over central america and in the south pacific carrying some of my personal gear put maybe ten years of use into them and its still going strong this included long plane travel bus travel in Central America and boat travel in South Pacific
have no idea about the arb bags
but I am on the hunt for some new dry bags for the roof rack area so will check out the arbs also
REI has some nice lightweight nylon coated ones ? but I am skeptical
I liked the dry zip bags but the zippers like on my dry suits need to much maintenance and went back to the fold over design in the past ?
I can say I like the clear sea bags I had when working on boats as I could quickly see what I wanted in them ? I also found I liked a few med size bags in a cheap duffel over a large bag as I could compartmenal everything and quickly get to what I needed
in a few rough weather situations I noticed opening one small or med bag was not putting the rest of my gear in the bad weather etc...
so part of me wants to stick to the clear med size of bags
OK update decided to order one of these ? from ebags $39.99
I have had a drypak that has lasted well also ? so seems like a decent bag
