As the owner of some pretty expensive dry bags, that I love and think they are great, I must say I'm very impressed with my Outdoor Dry Bag I bought for $7.88 at Walmart several weeks back.
While buying some camping fuel I came across them and initially chuckled and thought "oh how cute, Walmart selling WANT A BE dry bags". But then thought, "I can't go wrong buying a cheap one to put my charcoal bag in". Sure enough I did and it has exceeded my expectation and then some. I abused this little bag cause it was cheap, expecting to throw it away at the end of our trip. I think its going to outlast my $$$ dry bags.
Since, I've gone back and bought a 25L 30L and 40L with reinforced bottoms from the Walmart.
Just thought I would share. Life doesn't have to be expensive to be good!
