I bought this backpack for a trip to Europe recently. I have a more "tactical" style Eberlestock pack that I use for hiking as well as travel and road trips, but I decided I needed something a bit better-suited to the confines of airports, planes, trains, and smaller vehicles. Since I knew I would be spending my time in cities and similar areas, I wanted to blend in a bit more. I've been a fan of Peak Design equipment like their travel tripod and camera clip. I wasn't disappointed here, either. The fit and finish of Peak Design gear is very high. The stitching is precise and each piece is nicely finished. The layout is similarly well-thought out. The main zipper is well-concealed against the user's body, which is nice for theft protection. The straps are comfortable and tuck away easily, which is great for stowing under an airplane seat. The fabric and zippers appear to resist rain well. I didn't have a chance to stand out in the rain long enough for it to become truly soaked. The interior pockets are extensive and well-designed. I know it is rather at odds with the design philosophy, but a hip belt that stows similarly to the straps would be fantastic if you're carrying a decent amount of weight for an extended period. That's a reasonable compromise here because the pack is sleek and unadorned with MOLLE webbing and other features you would find on a more "tactical" backpack. That plain design makes it very well-suited to urban environments where it will be less likely to draw attention. I have one of the tech pouches which fits well with it. Overall, the pack is spacious without being bulky and comfortable for typical travel. From a purely aesthetic standpoint, I love the sage color, too. It's a bit unique, but fits my love of nature, too. Peak Design puts a lot of R&D into their products and it pays off. This backpack is no exception.

Recently went on an extended weekend trip and brought this Peak Design Backpack on the plane. It held everything I needed and then some. Expanded to 45L which is great if you need extra room and the airline (Air Canada) allowed. It fit into the overhead compartment. Extremely durable material, along with creative & practical design makes this a great backpack for travel. The quality of the materials are high performance. The pulls are really tough, the zippers don't get snagged and are very high quality. Many compartments to house different items so you can be very organized. Almost everything about this backpack is wonderful. The only thing I can say that they can improve on is the shoulder straps have a sternum strap, which is not easy to connect to the other shoulder strap. Maybe use a better system, with two sternum straps with a metal clip on both ends that clips onto each other. Other than that, a real quality product. I hope to use it more in the near future. I will use it as my exclusive travel backpack.

Great bag, built extremely well and had just enough space for my uses. It fit my 17-inch laptop despite not being advertised to be able to do so although the fit was somewhat tight, so that was a welcome surprise. Plenty of smaller zipper compartments inside the bag to organize and sort all sorts of things, more than enough for my use cases. Used this alongside the Peak Design travel duffel 50L and they both worked perfectly as plane carry-ons.

Pros: truly excellent design. Many features and well thought out design that make for a great and functional user experience. The hidden Pockets, unique strap stowage design, premium material, sizable water bottle holders on both sides, and much more. Cons: it was not the most comfortable to wear. The straps were a shorter length for this size bag. The waist strap was very short, it couldn't be removed but was easy enough to stow. They were uncomfortable, but similar products felt better. (I am taller and larger than the average person, most would find it suitable I think) I did really contemplating between this bag and another, unfortunately the other won out. I still look forward to their products in the future!

Very nice travel backpack. I like big backpack so for me the size is perfect. It seems very durable and very comfort to use. This backpack is rather on the expensive side, but the quality is good.

This item gets a lot of returns, and I bet it's because people get it to try it out but end up going with something that better suits their uses and is cheaper. The quality is obviously very high so I doubt it's due to defects. The biggest flaw (no comfortable handles) is easily fixed. While it has great "grab handles" in strategic locations for putting it on, taking it off, and getting it in and out of vehicles, it doesn't have good handles for carrying when you're not using the backpack. Simple solution: use any shoulder strap clipped to the handy attachment points. They're not intended for that, and look like it might be off-balance, but it turns out it works quite well. It's narrow, so you'll tend to use it with smaller compression sacks. While it's a decent packpack, it doesn't have load lifters, so while the hip belt is good enough to carry the load, your shoulders will always carry part of it -- how much depends on your torso length. I'm 6'1" but long legs so medium male torso, but my shoulders carried about 1/3 to 1/2 the load. I tried to rig up some load lifters using the attachment points and it almost worked -- it would have worked had my torso been an inch or three shorter. So, this is NOT a long trek hiking backpack. Almost but not quite. The pockets and access points are nicely laid out and useful. It does weigh an extra pound or two, but once I get 30-40 lbs of stuff in it, that doesn't matter to me.

TL; DR - Amazing backpack if you travel a lot. Very durable, packed with features I'm a who loves backpacks, especially ones that fit my exact needs. I travel around pretty frequently and always try to pack as light as possible. Always trying to avoid checking a bag when I travel and only using carry on's. This backpack has always been on my radar, but just couldn't stomach the price. Eventually, the little voice inside my head that's always whispering "treat yo self" finally got the best of me. And I took the plunge. It got here right before my 3 week trip to Europe. As soon as I got it, I was blow away with all the hidden features that it had. Peak Design is very good at not just product design, but also integration with its other products. I paired this with the small camera cube and medium size packing cube. The ideal set up for this bag in my opinion. I can carry most of my camera stuff in the camera cube, and about 4-5 days of clothing in the packing cube. With some room to spare! This set up leaves a small cavity at the top of the bag which I used to put with my toiletry bag or my Bose QC35 headphones along with a travel blanket. It all fits very snug and fits like a puzzle. The hidden straps at the bottom of the bag were way more useful to me that I really thought they would be. I typically travel with a crew neck or hoodie because airplanes are typically cold, but when I'm walking around or its warm at my destination, I'll take it off and use the straps to secure it on the outside of my bag. I've also used the straps to carry a blanket, works beautify and its very secure. The middle diver in the bag can be unzipped and folded away if you just want one big sack to work with, I prefer to leave it in place, has a well padded laptop and separate tablet compartment, and a few hidden pockets in the bottle holders. My only gripe with the backpack would have to be those afore mentioned bottle holders. I feel like they don't hold bottles snuggly enough. But given everything else about this bag, I can can't deal with it. The zippers are very solid, and water resistant, as is the whole bag. Personally tested this out when walking around Paris in the rain. My belongings were perfectly dry inside! Another big feature about the bag is its stow away backpack straps and waist belt. I always remove the waist belt of any backpack I get because I hardly use it. In this backpack, you can't remove them, but they do fold away behind some cleverly designed magnetic flaps! And when they are stowed, you don't feel any weird bumps and won'y even know they're there. You can also stow away the backpack straps under those same flaps and make this thing a full blown duffle bag. Which has come in handy more times than I would've thought. Final thoughts. Given how much I travel, I wish I would've bought this bag sooner. Cant recommend enough! The Value/Convience factor is just as high as the price haha. But well worth it.

Sometimes you want to wear it like a backpack, and sometimes you need to put it somewhere (in my case, an overhead rack on Amtrak or an airliner). When you need to stow this, the straps hide behind a cleverly engineered panel with a few magnetic catches to keep the result flush and tidy. The straps don't catch on anything. Then, to wear it again, just pull the straps out in literally three seconds and shrug it on. Genius. The rest of the design is simple and effective. It's mostly a one-big-bag design but you do get water-bottle pockets on each side and a slot for a laptop. The fabric and stitching feel sturdy and abrasion-resistant. It's not cheap! But it's a high quality piece of travel kit, and its thoughtful design means you will want to use it, and you will appreciate its better-than-most utility. (I also bought Peak Design's matching Wash Pouch to replace a 45-year-old Dopp kit that was fraying and disassembling itself at last. The Wash Pouch is, like the backpack, a clever critter. It has just the right combination of small and large interior spaces to hold deodorant, toothbrush, toothpaste, shaving essentials and smaller stuff like wipes, Q-tips, nail nippers, whatever... while keeping wet and dry things separate. )
