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!

Incredibly flexible yet very streamlined backpack
I've already used the backpack a couple of times and am extremely satisfied. Not only for outdoor adventures, but also for city trips lasting several days. When the backpack is empty, it has a very slim profile, but if you need more space, this is no problem at all.

shows promise!
when I unboxed this I couldn't for the life of me figure out how to open it. so I had to look up how to open it videos on youtube. I don't enjoy tutorial videos, so that was a bit annoying. however once i watched the video, it is super simple to open and close. quite innovativeand novel! o People in the street comment on how comfortable it looks, but after carrying my full kit in it I didn't have that same experience of all day comfort. I really miss a full size tripod holder. the hip belt came off the other day whilst it was folded up, and it took a few minutes to reattach it in the dark. but when not in use it does fold in snuggly I love the options of cordhooks and gear loop system however have not yet made too much use of this except for chest straps. I am disappointed in the amount of pockets available, to organise my gear.

Brilliantly practical
I bought the 45l outdoor backpack for longer trips. I found it big enough for my needs in order to avoid checked-in luggage (something I'm allergic to, mainly because of the long queues at the luggage lane and the concept of luggage lottery). It did an excellent job, although sometimes "sacrifices" had to be made with regard to the things I could put in. It's a brilliant piece of kit, but 3 weeks is a long time, apparently. Anyway... let me try to provide some useful information here, if possible: - it's great for carrying a lot of stuff over a lot of days and territory. It can take quite a lot of stuff and abuse. Many suitcases were thrown over it in the back of the bus and it braved without a wince or protest. It can also take verbal abuse, I think, but I only had words of praise for it so I can't confirm. - it's also quite light, too, which is convenient. Things change if you put rocks and anvils in it, but that's on you. The bag itself is by no means a porker for the amount of stuff it can take. - sometimes I wished for a few more pockets, but with a bit of planning and a few organising cubes (I had 2 from PD and a few from amazon basics) it did a great job to hold all my stuff in place. And I could find said stuff easily, as well, without too much digging. Of cube was for toiletries, one for cables and adapters and backup phone etc, and 3 for clothing. I'd try a few more cubes next time. Still, a few more pockets never hurt. Never. Ask anyone with cargo pants. - the closing mechanism -the lace thingy- made me nervous at first, it seemed weak and vulnerable and unlikely to hold together all my things. It did, though, and it's quite a clever system. With a full bag it's a bit optimistic to operate it with one hand, but most of the time it is actually doable. Combined with the roll-up system that secures in place with magnets, your stuff is safe inside and has no chance to escape accidentally. - the closing mechanism -the lace thing-... no, you're not having deja-vu, I just want to add one more thing. It really is more sturdy than it looks (it doesn't look very sturdy). After +3 weeks of frequent use, I didn't notice any flimsy-ness, slimming or falling apart. I don't know what material and sorcery it's made of, but PD did a great job with it. - the external flap/compartment is quite convenient for packing a jacket or a larger piece of clothing. The things you put there may not be as well protected from the rain and dust as the things inside, but if you're not going through rain on a dusty road during a volcano eruption you'll be fine. - the side pockets are generous and hold stuff well. I'm a bit paranoid about pockets without zippers or snaps or velcro, but these elastic-y things seem safe enough to make me assume I'll still have my things in them at the destination. - I haven't used the straps for big things like a tripod mount or those tennis racket things you use to walk on ice and snow, but you can attach quite large items with them. A tripod would look a bit too much when your camera is the size of your phone (and it's not a big phone, not even the XL or Plus or Max), just like those snow racquets would look quite silly on a beach walk in warm weather. Should you want to, though, you can attach big things to your backpack with said straps. - the waist strap is very convenient. It can take a few small things that you can access quickly; my camera kit that I discussed one paragraph above definitely fits. You can also put a few snacks, but snacks tend to evaporate whenever I'm around, no matter where you place them; proximity and ease of access are key. The strap is convenient though. And very easy to remove if you don't want it. - this dark red/ burgundy/ inside-of-a-cherry colour looks great. Of course, if you're an accountant or actuator I'd suggest something more grey or beige. However, I enjoy being able to identify my bag easily in a large pile of luggage at the back of the bus. Nobody needs 3 suitcases, Alice! Anyway, I received compliments from the ladies about the colour. Yes, even Alice. But then she laughed its size. Go figure... All in all, if you're not a hoarder this bad boy will take care of your stuff in style and comfort. And comfort is very important for me. It's still useful to be nice to other people on the trip because you won't be able to carry a bottle of wine with it through airport security. But otherwise, it'll serve you well on your adventures. Or on your trip to the audit maybe, if you went for the grey colour.

Lovely backpack full of great features
I purchased this backpack as a replacement for my aging timbuk2 pack. I'ts mainly used for traveling, hiking and some bikepacking. The Peak Design Outdoor Backpack is a massive improvement. I'm over 2m tall and it fits great thanks to all the available adjustments. It stays secure on my back during hikes and on the bike, has massive amounts of storage and allows me to easily carry my Sony A6700 on the capture clip, either on the hip belt or the shoulder strap. I would advise to use the Peak Design Pro Pad when mounting to the hip! The included sleeve for a water bladder is great as taking of the backpack just to grab a sip from a bottle is a hassle, especially on the bike. The additional mounting points, straps and places where you can stuff gear is also great for some quick access items like rain jackets or tripods. It also fits nicely into overhead storage on airplanes or under to front seat if not fully expanded. The zips feel great, as usual with PD products, overall manufacturing quality is great too. I was initially skeptical about the PD "Ultra Cinch" closing mechanism for the rolltop but it's actually really great as it works one-handed and lets you compress items in the front pocket if you want to! overall: I love it! It works for all my use-cases, has massive storage and is still quite small if not stuffed full and having the lifetime warranty and built quality from PD makes the price acceptable.

Nice Bag
I have a few of Peak Design bags. Each has a best use. This one is the one that I take when I have a lot of equipment and it is heavy. The belt and the better straps makes it that I can take a really heavy load. Still caries a good deal and has a lot of flexibility. I am aware that some people have criticized the company for tracking you. But if you want your equipment to be warranted for life, then you are going to be tracked.. True for anything you have longterm warranties on. If this is a concern to you then don't register your equipment.
