I've had a watershed occoee for 7 years of full time guiding and it's still super dry and in good shape. Spend the extra money and go with the watershed. you won't regret it.

i only have one watershed bag - the ocoee, and it's awesome.  it's what i pack my sleeping bag in usually because i can't afford for that to get wet. 

A friend of mine brought some of the sealine zipper bags on The Grand and had the zippers fail on day 4 of 21. Not sure if this is a problem with all of them, seems like the sand didn't agree with the zips, but they might be a good option.

I have 5 watersheds. The Futa's are bomber. The Ocoee and Chat are also amazing.

I have a little Yellow one that is not even mine, but I have been holding onto it for the owner around a year now. Of all the bags I have, this is my go to bag. I have seriously beat the crap out of this thing and it still works just great. I use it not because it is a size I don't already have, I always grab this one because it's not mine! Trust me they are worth the extra money, just don't loan them out, because imagine how mad you would be if you found out someone was using it to store fishing bait in...

Am I the only one who uses a peanut butter jar with a carabiner ducktaped to it?

Yeah, I do use a variety of sizes of Nalgene bottles for various dry purposes.

I tend to use the peanut butter jars for sandwiches and other noncritical stuff. They will leak if they get squeezed or disformed, but sandwiches in baggies and such usually survive well anyway. So far, so good. The main thing I like about these containers is that they are lighter weight than any other container I've come across. I also have a gallon size mayonnaise jar that is a bit tougher and drier and surprising lightweight, compliments of the Goodwill Store, which happens to have weird stuff like that. It is still lighter than any drybag I have. It's my main lunchbox these days.

I use a Pelican box for camera equipment. I like the crushproofness of the Pelican boxes.
