Handy Features:

1. One of the most heavy-duty bags of its kind
2. This bag is actually waterproof, unlike some other dry bags on the market
3. This bag features a practical loop, which is very handy for connecting a strap to.  The loop is not necessarily to be trusted if the bag is very heavy.
4. These dry bags come in a variety of sizes

Drawbacks:

1. This bag is not squirrel-proof

Tips:

1. When hanging this bag from a tree while backpacking in bear country, hang it at least 10 feet out from the tree trunk and 5 feet down from the branch (link to bear article)
2. When hanging this bag from a tree as mentioned above, use a thin, slippery rope as opposed to a rough or thick rope: red squirrels can easily climb down thick and/or slippery rope
