Note that the Lowepro Pro Trekker 400 AW has been replaced by the Lowepro Pro Trekker 450 AW. I love camera cases and backpacks (and have way too many), but I had not tried any of the latest-at-review-time Lowepro Pro Trekker series and have been very interested in doing so.

I needed a backpack that could easily carry the 400mm 2.8 and multiple bodies. I am able to carry two full sized bodies and a compact bodies along with a 24-70mm 2.8 & a 70-200mm 2.8. Plenty of room for a 13" or 15" laptop and other accessories. This backpack when fully loaded is heavy. Very heavy.

I have now purchased my second Pro Trekker 450 AW and couldn't be more stoked. I run a full service production company providing film and photography services worldwide. I absolutely abuse gear with the amount of travel, austere locations, and harshest environments.

Purchased this product for my husband. He has had many low back surgeries and needed a way to carry all his gear without back strain. The pack is ergonomically designed to distribute the weight evenly and my husband tells me it is quite comfortable fully loaded.

There's nothing more frustrating than not having enough room, or having to layer gear in bags thus making it hard for quick access. The capacity and flexible compartments in this pack make it ideal for just about any photographic outing.

I bought this for a trip to Costa Rica, it served me well on an intense birding expedition, and continues to protect my gear or all my travels and hikes.

This bag is awesome for travel to remote places, or when you just need your entire kit. I've used this bag to carry lots of items, and combos of gear that might make your head spin.

A harness system that can be tailored to fit your torso perfectly, allowing this monster bag to carry an amazing amount of gear at ease. It's also the most protected gear section I have seen (compared to F-stop / mindshift).

I bought this backpack looking for the best option and it has not let me down. You can carry all your equipment and the protection you are looking for.

I shoot most every weekend and I love it, very customizable. I have had this for 5 years and I never had issues with wind, rain, or heat with my optics.I do not see this pack on the website today. Bring it back..

This is without a doubt the best camera backpack I've ever used. I've had it loaded up with 2x 5D MIV bodies, 6x Canon L lenses, two flashes, ball head, and more, and the distributes the weight across the hips and off the shoulders like a high end trekking backpack.
