This field pouch is "just right" for so many things. Most time I use it to carry my (big) phone, or my (small) camera, a packable nylon shopping tote, EDC knife, dog treats, and whatever I just don't want stuffed in my pockets. People like the look and style of it, too.
This thing is as beautifully-built out of high quality materials as you'd expect from anything Peak Design. It's well-laid out, adequately padded, and feels like it'll last a dog's age. I got the blue one, and leather accents and blue stitching look great, though I wish PD still offered the warm brown colorway they used to. Just note that it's probably quite a bit smaller than you'd think: I bought it hoping it'd fit a Leica M10 with a small Voigtländer lens plus either a second lens or a tiny Ricoh GR body—a little daytime kit bag to keep on the passenger seat of the car or in a backpack. Turns out the M just barely fits when placed horizontally (bottom plate down, lens facing foward), and definitely not with a lens hood attached. When placed vertically (side of camera down, lens facing forward), because the roll-top style allows vertical expansion, it fits a bit better, and just leaves enough room for another small lens to the side. In other words, it *does* more or less fit what I'd hoped it would, but it's snug snug snug and smaller inside than, say, a run-of-the-mill fanny pack. Just know that most ILC mirrorless bodies won't fit gracefully, unless fitted with the sleekest pancake lens you've got. Should be perfect for something like an X100V or smaller, though. It'll be great for holding the Ricoh on its own, plus an extra battery or flash trigger.
I'd also say that it most definitely works best as a bag insert—something to keep your gear safe and separate inside a larger bag—rather than as an on-its-own tote. It looks super silly when strapped to a belt unless it's nearly empty, and you just wouldn't catch me dead using it with the provided strap. The strap's pleasant enough, and it attaches nice and securely, but there's just no human way possible to hang it on yourself without looking like you're carrying the least stylish discount store 1990s mom purse of all time. If that's your vibe, rock it. If it's not, which is probably the case for most of you, just keep the strap off and use it as an insert.
Overall, it's a wonderfully-built, cozy little dumpling wrapper if you've got something small to fill it with.
I carry a number of cables in my backpack and had been looking for a way to organize them. I bought this for that purpose and it works perfectly. I have the 20L everyday backpack, it’s a tight / perfect fit.
I purchased this a few months ago with the goal of using it on a trip to Europe. It worked out very well, EXCEPT that the inner zipper was a real pain in the neck to operate. In addition the clips holding the shoulder strap were not stable and came undone on several occasions, causing me to almost lose the pouch. Bad design here.
I bought this pouch for an everyday carry for things I hate to have in my pockets. Wallet, glasses, keys, phone. The size flexibility is great in case I need something more. It will even take my iPad Pro 11" vertically, although it does not close then and the placement of the strap is unstable and tends to want to flip the iPad out. My problem and I clip the strap to the top of the bag for more stability. The bag would be perfect for me if it was just one inch or a couple centimeters wider and then the iPad would fit fine horizontally on the occasions I want to carry it too.
I've used this for several months now as my EDC bag. Overall, I'm pleased with it. I just have one critique and one wish: Critique: I don't like the velcro. The velcro on the flap catches on my sleeves/clothing. It would be nice if the flap closed magnetically instead. Wish: I wish the pouch was slightly larger in all dimensions, but it's not a dealbreaker.
