Review Summary
Customer Images
Here's what customers have to say
The backpack is versatile and well-designed, with durable construction and comfortable fit. Reviewers praise its features like the rolltop, side pockets, and camera cube compatibility. However, some find the opening mechanism and internal organization less than ideal, and the weight when fully packed can be a drawback for longer hikes. Overall, it is a high-quality and functional option, though it may not suit everyone's needs.

Comfortable, durable and complex bag
I love this bag! I bought it for backpacking around Central Asia as a daypack that would also fit my FX3 kit and also as a cabin bag for the plane. It’s had plenty of scuffs and scrapes already (I’m two weeks into the trip) but it just bounces back. The mass of pockets is great for organisation. But when I first got the bag I fully ‘lost’ something because I forgot that those pockets existed! In hindsight sight I think I’d have been fine with the 25L but that’s my fault. I would definitely recommend it if you want something rugged, versatile and with plenty of organisation :)

Another Well Thought Out Bag
I cannot recommend PD gear enough. The thoughtful design of every element makes all the gear worth owning. This bag has clever storage both inside and out, fits comfortably for all the day hikes I’ve taken it on, and looks great!

Top Product 👍
Great backpack. The design is well-thought-out and innovative. The price is quite high, so I'm curious to see how the quality will hold up over time. So far, it's been performing great and has been very comfortable to wear on longer tours.

Spacious, versatile, and efficient!
I bought this bag a few weeks ago and it has been life/changing! I bought it with a large camera cube. The build quality and the customizable organization is top-notch. I’d highly recommend this product for wedding and event photographers. That said, this is not a bad bag to carry with you on long treks, if you like to do landscapes and wildlife as well!

The backpack that keeps on giving
I have just finished a 1 month tour of: ~Singapore, Turkey, Dubai, Tanzania & Kenya using the backpack. It’s amazing how each time I need space I find another surprise in a space or methods of using it. It wonderfully easy to add storage space no matter the size. I used it as a carry on and it is perfect.

Excellent hiking pack
I finally had a chance to take the PD outdoor bag on some serious hiking. I had avoided the previous PD bags due to the lack of a solid hip belt, so I used an REI day hiker with a small camera cube. That worked, but it was always frustrating due to the cube not being secure in one place. I love that i can secure my smedium cube at the bottom of the bag with the back panel access. My only gripe here is that the loops to secure the smedium cube with the c-clips were not perfectly aligned so it was tough to get a secure connection on one side. Never-the-less I made it work. I was worried about the performance of the roll top closure, however with the magnets to bring the sides together it actually works pretty well as long as you don't over fill. On my previous bag, I had the capture clip on the shoulder belt but after a long hike one of my shoulders would be sore and knotted up due to the weight on one side. On the Outdoor bag I tried mounting the clip on the hip belt. This was far more comfortable for me, though I could see someone being annoyed with the camera being near where you hands come to rest hanging down. I think you could get a bag that functions similarly at another manufacturer for less, however I've experienced PD standing by their lifetime warranty and if you can stomach the initial price then you know you have a product for life. All in all the bag is very functional and I'm super happy with the purchase. Looking forward to some summer hiking!

Unexpected Range Bag
Originally thought this would be a nice hiking camera bag but the large camera cube is actually pretty cramped. The back panel opening is just slightly too small to really access the entirety of the camera cube so that got a little annoying. So I went back to just using the large camera cube with the 35L duffel. The straps could also be more comfortable (kinda like Osprey packs) and the string sternum straps are a little fiddly to use so I stopped using them. The outdoor backpack is actually quite a nice range day bag and fits multiple pistol pouches in the main compartment along with ammo, ear/eye protection, and miscellaneous tools. The outer quick access compartment behind the rugged flap is perfect for my B&T GHM9 to be stowed away with the stock collapsed (the SBR measures ~19" and fits pretty well). The side pockets easily store rolled up targets and suppressor. It's really a nice surprise because the backpack doesn't scream range bag but fits everything I'd ever need to bring. In all, slightly disappointing as an outdoor camera bag but pretty awesome as a range bag.

Review after National Parks Trip
I used a 45L Outdoor Backpack for a Utah National Parks trip. The bag safely stored my camera gear (one body, two lenses, some accessories) along with my electronics, water bottle, and random other things. This bag is probably a little too tall to fit under the seat so I had to carefully place my feet on the ground. On the ground, it was good but I do miss the quick camera access provided by the Everyday Backpack. Due to hiking in rough terrain, I was not comfortable using a Capture Clip. It was quite comfortable hiking. I liked the chest straps, load lifters, and waist belt options. I think it's more comfortable than the Everyday Backpack. I would not place a water bladder beside my camera gear. The outer cover got marked up and maybe that's a badge of honor, but it looks nice when it's shiny so I used a wet cloth to wipe it down periodically.

Outdoor Backpack & Packing Cubes
I have Outdoor Backpack 45 l & several Ultralight Packing Cubes. Together they are a great and versatile combination for different use cases, be it a hike or a weekend trip.

By far the best backpack I ever had
I backpack around the world and I've used many forms of backpacks over time. This one is by far the best one I've ever used. Its extremely comfortable, fits amazingly well in the overhead bin, and is lighter than a lot of competitors in the same class. It isn't ultra light but it does offer various functions you don't find in ultra light backpacks. The back panel and carry system are absolutely comfortable. I've been recommending it to everyone I know!
