I am rewriting this review after a discussion with my husband about it.  His view of this bag is very different than my first impression.  I expected to love this bag.  YKK zippers, water resistant messenger bag design, Thule brand durability... But when it arrived, I was a bit overwhelmed by its size.  Even though the measurements are listed I just hadn't been able to picture how long this bag would be.  It felt very large to me.  This camera bag is for a professional photographer who carries a large telephoto lens, a full frame DSLR, an auxilliary flash, and perhaps another additional lens.  DSLRs that are not full frame cameras won't fit as well as larger cameras in this bag.  My Canon T3i does jostle around.  I am used to my camera fitting just right in a bag.  This bag was designed to allow a photographer to grow and adjust with their equipment needs.  My husband saw this bag differently.  He immediately loved it as he slung it across his shoulder.  He loves bags period.  He immediately pointed out the ease of adjustment to the shoulder strap, the attachment of the strap to the bag, the velcro closure, ease of opening the zipper, and more.  He loved it and believed that I will too as I use it more.  I do trust his opinion since it is he who buys purses for me.  He has a good sense about about the utility of bags and how they look.

So, what's to love about this bag?
--Weather resistant design features
--Easy and comfortable to carry all day long without hurting your shoulder or bag
--Because of how the strap is attached, you can unlatch the waist band (which steadies the bag) swing it around, zip open the top and easily pull your camera in and out of its home
--Padding design accommodates professional DSLR body with attached zoom lens (up to 70-200mm f/2.8) and extended battery grip
--Zipper access on top opens to the main compartment--zipper opens easily and does not snag at all because of the design
--Thin waist belt
--Strong, comfortable shoulder strap that's easy to adjust
--Room to store 3 memory cards, 2 lens filters
--Well made with strong material

What I don't love about this bag...
--It is a very bulky bag for a woman of small to medium build, like me.  When I look in the mirror with the bag on, I think look a little funny, but my husband says I look fine.
--The zipper opening on top would be easier for a person larger than me to use.
--If an extra piece or two had been included for the padding bag that could modify the padded insert bag for smaller dslrs, it would be a more versatile bag.  I think I need to play with how the inserts are placed in the bag a little more so that they will work better with my camera.

I am sure this is the right bag for a lot of photographers. I'm just not sure it is the right one for me.  It's perfect for my husband though, who is about 6' tall.  To see more pictures of the insides of this bag, go to the Thule website.  They have multiple pictures of the insert and examples of how the pockets can be used.  There are more small compartments than you see in the pictures.  The bag does also fit up to a 15" Macbook, which one of the pictures illustrates.  I would also recommend that you visualize the measurements of the bag to make sure this is the size you are looking for before you purchase it.

This is a strong bag that will do the job it was created for well. If you are tall and have a large camera, I'd definitely check out this bag.  It would be very comfortable to carry around all day with larger pieces of camera equipment.  The strap is extremely easy to adjust and the strap pad is nice and long, which makes it easy to swivel around on your shoulder when you need access to the bag's contents.  As I've mentioned, I am used to smaller bags and am of a smaller build.  But, if I were going on a day long sightseeing trip and wanted all of my equipment with me, this would be the bag to use.
