while at Walmart looking for a new dry bag (DS just upgraded to a bigger backpack so needed a new dry bag for his kit) I decide to try this - Coleman Dry Bag)

Things I like so far:
-It was the same price as the other ones in the same size
-it's clear, which should make it easier to find stuff inside.
-it's thicker material, easier to stuff and unstuff, and clearly rip-stop
-fits nicely inside my hiking pack
-the velcro is inside so that one side has to reach across the contents instead on meeting in the middle, which means the other side covers that one like an envelope

Things I don't like so far:
-it's thicker material (plasticy instead of nylony) so heavier
-it dosen't have as much velco to seal the closing (1 piece, a couple of inches long, in the middle of the opening)
-the velcro is inside so that one side has to reach across the contents instead on meeting in the middle, which makes it harder to close when full
-it's not able to roll closed making it more water tight

So far, not bad for $11. We'll see how it holds up.
