Question: Is it waterproof without using the all weather cover? What type of material?
Document: this product was more than i needed. but i think it should improve on the velcro inserts inside the bag. the  velcro need to have more stronger of a grip to the inside material. also a neat feature i like it the weather cover hiden beneath the bag. it served me well when i used from my studio to my car during my rainy day. a great product to have.
I bought this because I had a small lowPro bag. I have Nikon D40, 18-66mm, 50mm, 70-300mm, 35mm, and many filters, remote control, cleaners, 2 mini tripods, digicam, laptop and music set which I was unable to put in my previous bag.This bag is bigger/strong with lots of pockets/sections than I though. You can adjust the rooms/section using provided pads. Outer material of bag is pretty good and weather proof.
Gave it 5 stars for the way it's made and pricing. Very durable, lots of space, the weather cover looks functional, put in a nikon with 2 extra lenses, a fujifilm and Sony cameras not counting filters (over 50) and other accessories. FINALLY!! All my camera stuff in one place!
(plus it's pretty hard on the shoulder)Without the tripod/monopod attached, this just looks like a standard backpack, just with a a lot of straps and things.Bonus - built into the bottom of the pack is a rain guard you can pull out and completely cover the bag with. It seems a little difficult to situate well over the bag and keep in place.
reasons to buy this bag..1)ITS CHEAP! 2) its well made. zippers and material are rugged and durable. 3) if you're like me who don't like switching lenses and carry 2 camera bodies with lenses attached. 4) u can carry additional lenses and flashes. 5) u can attach a tripod on its side. 6)  it has a rain cover to protect your camera from the elements.
And one of the best parts.... it fits airline carry-on requirements!Features that prove the manufacturer's commitment to quality.... I'm not sure exactly how to word this, but they are locking straps that go over the zipper to the main compartment... basically for those of us that tend to stuff our bags, the straps help keep the zipper from breaking (thank you, Aktiv!) Also, there is a waterproof cover hidden in a pocket in the bottom.
This bag is not too big..not too small. It has all the bells and whistles you'll ever need. Very convenient for any type of shoot.
Because it met my expectations. The merchandise is of good quality and was delivered without change.I liked the fast delivery and safety in trading.Yes, I would recommend this product to my friends
Great product very practical  for traveller and its equipamiento most valuable , included more severe weather condition must have for every  entusi&aacute;stic people
Pros:* Sturdy Construction* It is very large and holds lots of gear. * It is well made and has lots of space. * There are plenty of Velcro dividers so you can setup the interior to suit. * It is well padded for protecting your gear. * The belt strap makes it very easy to carry without killing your back and shoulders.
Answer: The weather cover is conveniently located and attached at the bottom of the pack, super easy to deploy and return to its place. I am not sure of the material, however if you were concerned about rain I would spray the pack with 2-3 coats of a water repellent (3M scotchguard) AND the cover as well. If you are concerned about dropping it in the water consider a good water tight bag to cover it with. I live in the NW. It rains a bunch. It works great.
