At first I ordered the Lowepro ProTactic 450 AW II not realizing how big it was, only to return it for theLowepro ProTactic 350 AW II that was smaller. Both are excellent backpack style camera bags, but I was looking for one that would be the easiest to travel with without being too large. My criteria was to have a bag that I could easily carry on an airplane and that would fit under the seat. I'd recommend either bag for their identical features with the following considerations. The 350 is roomy and adequate for just about all the camera gear you might need for travel. I carried My FX size DSLR, a beefy 20-70MM zoom, and 50 and 135 mm lenses. Additionally I carried an on-camera strobe, battery chargers, and my mini tripod on the outside. I was also able to slip my iPad into the designated pouch. I must state though that will all of my gear this bag was heavy, but perfectly sized to fit comfortably under the airplane seat. While the 450 was bigger and capable of carrying more gear, I just couldn't see wanting to stuff it any heavier than what I had already fit into the 350. Bottom line is if you need more capacity the 450 is your choice, but otherwise the 350 is probably big enough. Besides size, both of these bags were well designed with easy access from the top, sides or fully from the back for easy access to your gear. A feature I really liked is the detachable belt that can be used to carry accessories including smaller lenses around your waist for day use. I wore the belt the entire time on days during our vacation, carrying one or two extra lenses and essential accessories.

This backpack is a beast. If you just have one camera and a couple of prime lenses, this is going to be overkill for you. Look for something smaller.It is a very large, spacious pack with thick sidewall foam lining and heavy duty durable zippers. The back has air channels to keep things cool on long hikes, and the detachable waist strap helps with stability for long days of work. The backpack opens mainly from the back, which is a nice security feature. The main cavity has a ton of different dividers of differing thicknesses and lengths so that you can customize your load out. Each side has an opening for quick retrieval of a camera. The back also has a very well padded laptop sleeve that can easily store a 15” laptop. The pack also comes with a set of accessories to further customization. This includes two adjustable straps, a water bottle pouch, a zippered pouch, and a sleeve for the base of a tripod to tuck into. I am currently using that and one of the adjustable straps to secure my tripod to the outside of my pack.I love this backpack and all of its features so far. It is so convenient for my profession, where everything is quick and spur of the moment so I need to have my equipment easily accessible at a moment’s notice. It is a bit hefty, but incredibly comfortable. I don’t even notice the weight anymore because of the comfort.There are a couple things I think it is worthy to mention for potential buyers: I wish it had a little more padding in the bottom. I took the extra dividers I didn’t need and layered them on the bottom because I felt like that’s the one wall that didn’t have quite the protection I hoped it would. Also, this pack is super padded other than what I just mentioned, so it does have a bit of weight to it. I’m guessing it’s around 3-4 lbs., so it may not be the best for really long treks. Finally, I’ll reiterate that it’s a huge bag. I have one walk around lens, two primes, one body and a telephoto, plus video accessories like mics and handles and a monitor, and I STILL have a bunch of space left over. It is almost too big for me. I’m okay with this because I plan on using the top half as another suitcase for my upcoming vacation, but if not it would beg the question if I needed something smaller. Just keep that in mind.For professionals, especially photographers working with multiple lenses and more than one body, this would be perfect for you. For others, as long as you have plans for the extra real estate left over, you will find this backpack equally as enjoyable.

I’ve had the 450 version of this bag for years and just purchased the 350 for something more travel friendly (smaller).Pros:- Rugged. This bag has a hard top and back, firm bottom, and I feel totally comfortable slinging it around or tossing it on terrain to get things in and out. I also love that the rain cover is attached (just dry it before repacking obviously)- The detail! The inner zippers zip into a protective corner so they can’t scratch your gear. There are several quick grab compartments, while keeping the main opening on your back for theft prevention. Outer zippers have pull tactical grab tabs. There are transparent inner pockets so you can see quickly what’s stored.- Hiking/lugging around: the straps are super padded and the back is fairly padded. There are adjustable waist and chest straps to distribute the weight. The waist belt can also be removed and used as a utility belt. There are a ton of places to attach items to the outside like a tripod or water bottle with carabiners or straps- Durability: I’ve had my 450 for about four years and it genuinely looks as good as it did when I got it. It’s been tossed on dirt, sand, rocks, and you wouldn’t know it.Fit: there’s so much room for gear and lenses. The best part is, I can fit my 600mm while attached to the body and still several other lenses!Cons: because of the durability and ruggedness, it’s a little bulky and heavy. Also, the 350 is not very wide - which suits my needs for travel but, does mean some taller lenses may need to be laid on their side vs standing up.
