I received the bag promptly and the bag is made well enough to trust it holding a fairly expenses camera and lenses.

I previously purchased this bag in March 2010 and have just purchased another, October 2013. Originally purchased for some photo equipment it was primarily used to transport weights for placement on lights stands to keep them from being knocked over. When not in use the bag and weights were thrown in the back of a truck or trunk. It has withstood that with about 50 lbs of weight being carried in it and still looks decent.

It's utilitarian look keeps others from knowing what is inside, is heavy canvas, and the 1 lb 7 oz weight makes it a light weight messenger bag when compared to LowePro, TimBuk2, and others making it a discreet camera bag. The bag is great because it can be folded flat, packed for travel and then used when on location.

The canvas strap is 1 1/2" wide and can be adjusted from 26 1/2" - 51" so can be worn close to the shoulder or cross body and even on a large person still have the bag rest on the hip.

The large inside compartment I've measured at 11" x 9" x 3" but because it is flexible you could inset something larger in any one of the dimensions. I've added a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ciesta-Arco-Flexible-Insert-Mini-Camera-Padded-Bag-Case-Mini-Dark-Brown/dp/B00C0OFDYC/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ciesta Arco Flexible Insert Mini Camera Padded Bag Case - Mini (Dark Brown)</a>&nbsp;into the bag providing a place for a camera and lenses from colliding with each other with enough room for some other equipment around the sides and under the insert.

The back slide-in flat pocket will hold an iPad in a case (snug fit - a Nook HD+ and case slides in easily).

In the main compartment there is a zippered flat pocket that is 7" x 5".

Two larger flat pockets on the main body under the flap are 8" x 5" wide. There is another flat pocket on top of one these and under a card holder (holds about a dozen business cards easily) that is almost 7" deep x 5" wide.

The front two small pockets are 4" x 2" x 1" but flexible enough to put something sized 3" x 2" x 1 1/2". Anything larger and the Velcro flap is not long enough.

The two side pockets are 6" x 2 1/2"  x 2" and can hold something about 2 /1/2" diameter x 5" tall like a 20 oz water bottle (snug fit).

The front cover flap is secured with an adjustable strap and slide in fastner so you can overload the bag and still secure the flap and help to prevent theft and things falling out.

It is not waterproof but sheds some water and could easily be waxed to increase it's water resistance. I washed my bag to increase its flexibility.
