Thick, but nice.

I have not put this bag to the test yet, but it keeps air in so I assume it will keep water out. It seems very sturdy and well made. Should last a long time if treated correctly. Be advised that the material that this bag is made of is fairly heavy, which makes the bag a bit heavier and quite a bit stiffer than some of those lightweight bags you may have seen. Still, I'd trust this one farther than any of those to take a licking and keep on ticking!
