Question: Does the bag come with a rain cover?
Document: If I could change one thing about this, it would be to reduce the lumbar support by 1/2 to 3/4 of an inch because it sticks out just too far.The only failure I've experienced with this bag is an area on the right hand side where the shell has somehow come unstitched for about 4 inches near the top flap.
I actually didn't expect this bag/backpack to be so big. However, it makes sense and it holds allot of equipment and the Sony 15.4" laptop all in one bag with good solid construction and padding along with some light rain guard on the outer areas. It fits well, is very adjustable, comfy but heavy especially when filled. However, to me that is a no brainer. If you are looking for light weight this is NOT it.
I am able to fit the bag under the seat of regional and large jets.
I have not experienced any issues with these so far, though my time with this bag has been short to date.I highly recommend this bag to those that have expectations similar to mine.
This is absolutely the perfect photo bag for me. It's comfortable, rides well, carries everything I could need in the field, including a tripod. I think the design is by far the best so far.
A must have, This is a Bag of all Bags, Holly cow!Great Buy, Very happy with it, dont think i would need another, but would buy another one if needed, and very happy with this purchases.
Just like the title indicates, this backpack is a great pack for carrying gear. The design of the packs straps, and lower back support are well positioned for a full bag of equipment, and does well over long hikes in rough terrain.
It holds everything, and I mean EVERYTHING!!!! !It has every compartment in the world, and what is shocking is that there are 2 bigger versions of this bag, plus they sell over compartments for other things.The out side is big and bulky, but that is because of all the padding, compartments and such. you can squeeze everything down using all the straps and such that it has. It will def.
This thing is HUGE. If it was white, one might be mistaken for an Apollo astronaut preparing to walk on the moon. For some, the size will be too big but for me it's just right. Having a large bag like this allows me to not only carry multiple camera bodies and lenses, but it also allows me to carry a plethora of accessories into the field when necessary.
This is a great bag. Build is awesome. I have a sigma 150-500mm in this, as well as 135mm, a sigma 150mm macro, an 85mm 1.8, a sigma 50mm 1.4, a 17-55is and a 70-200 f4 is. It's a beast, and your not going to want to carry it around town.
Answer: No it does not come with a rain cover.  The exterior is water repellant but I always put a rain poncho over the top if I am shooting in a downpour (in Arizona that doesn't happen often but when it does it's like Noah's Ark kind of rain).
