Let me start by saying that I have many Pelican hard cases.  I my opinion, Pelican hard cases are the standard by which all other hard cases are measured.  However, this soft backpack falls short of expectations from a price / value perspective.  This backpack is listed on Amazon for $190 at the time of writing this review.  That is steep.  So... is it worth it.  Probably not.  The main selling point of this backpack is it is waterproof.  It has water resistant nylon outer shell (which is not particularly unique), and water resistant polyurethane coated YKK zippers.  The zippers might be water resistant, but they are not very user friendly.  Basically, there is an extra flap on top of the zipper teeth, but under the zipper slider which covers the teeth to make it water resistant.  In practice, this makes the zipper very difficult to zip and unzip.  Like I said, it is not a very user friendly zipper.

However, the zipper is not my only gripe.  You see, for a $190 Pelican backpack, the Pelican logo so proudly displayed is an iron-on sticker.  The logo is not even embroiled onto the backpack.  I am almost certain this logo will come off after a few uses.
In conclusion, if you search for waterproof backpacks on Amazon, there are over 2000 hits.  I just don't see how this backpack is any different than a $20 backpack.  And if you want to get really fancy, a $50 backpack would likely do.

Sorry, I really like Pelican products.  But just not this one.
