Thanks so much for this... Looking at both of these currently

My humble opinion from real life experience with both these slings and more: 6L as well as 8L are very controversial volumes, cause when I have my very minimalistic EDC consisted from keys, small wallet / cardholder with minimum spare cash, smartphone, pair of small in-ear bluetooth headphones, medium-sized powerbank (up to 12000 mAh) with cable, maybe some small pocket knife as an extra and this is it: - I literally don't need 6L / 8L of volume at all, it's far too much just to empty my pockets! Thus, it's quite the opposite = much smaller fanny pack / waistbag / mini sling with up to 4L - 5L of volume max(!) will do the job perfectly fine, sometimes even smallest one like 1L Osprey Transporter Waistbag or 1.8L Deuter Belt Hipbag or 2.2L Osprey Daylite Waistbag are sufficiently enough just to empty my pockets and provide one convenient proven grab-n-go storage for every smaller necesseties from keys to cardholder not to forget something important in the pocket of other jacket when I go out and about! Besides, both of these given medium-sized "too much of spare volume" slings aka 6L Ospey as well as 8L Patagonia severely lack dedicated secure zippered / hidden pocket for valuables like wallet = it's a huge flaw for both of them, not to mention the lack of organizational pockets for smaller items, while modern +/- 2L waistbags like Osprey Transporter or Deuter Belt as well as minimalistic +/- 4L mini slings like Tomtoc EDC Compact Sling or Alpaka Bravo Sling Mini v2 are far better in these specific matters = keeping your valuables safe from thieves and your smaller items well organised! It's utterly important advantage for Tomtoc and disadvantage for Patagonia just to illustrate! At the second thought, when I do have to bring with me not minimalistic but rather modesltly expanded EDC, which includes not only some small tablet or kindle in addition to smartphone and some small yet powerful GaN charger in addition to powerbank, plus maybe big over-the-ear bluetooth headphones and/or bigger wallet with my passport and multi-currency cash as well as must have thermo bottle / flask with hot tea or coffee and some extra layer of cloth like rain jacket (or umbrella at least) or vice versa sunglasses in volume eating protective hard case (depending on weather forecast) as a must: - well, 6L as well as 8L in this case scenario are just not enough at all!!! Cause I definetely don't want to put even the most reliable and leakproof flask inside the sling next to my iPad mini indeed, not to mention umbrella does not fit in these small or medium slings anyway, while rain jacket would strictly compete for a place with big headphones (so I need to choose between headphones and extra layer of cloth which is irritating!) and maybe rain jacket could be an option only with Patagonia thanks to its compression straps and still - not an ideal solution at all! In other words, for expanded EDC I'd rather prefer something like small EDC backpack already with higher volume = 12L Alpaka Metro backpack or 14L Deuter Bike 1 backpack will do the job much better than these mediun 6L / 8L slings, cause backpacks capacity will easily handle umbrella plus thermo bottle, where even 8L Patagonia Atom Sling would have a lot of issues and unwanted compromises actually! To tell the truth, for expanded EDC my ideal sling was already discountinued Thule Crossover 17L sling and it had it all = external water bottle holder not to worry if leaked liquid will kill my gadgets, hidden zippered pockets to keep valuables safe, enough capacity to put umbrella as well as big headphones and extra layer of cloth in addition, plus a bunch of small organizational pockets for smaller items to be organised well without clutter and mess! At the end of the day, at summer with minimalistic EDC - I love to use 4L Tomtoc Compact EDC sling and dream to upgrade it towards even more advanced 5L Alpaka Bravo Sling Mini v2, while in midseason and winter I actually found my way with 8L Patagonia Atom Sling, BUT! But I had to buy Thule Subterra Power Shuttle Mini Organiser in addition for powerbank, cables and small bluetooth headphones not to create the real mess and clutter inside two big compartmens of 8L Patagonia Atom Sling, I had to agree I would not bring big headphones with me anyway and I won't try to put wallet inside the Patagonia Atom Sling cause it's simply an invitation to thieves so I risk to forget my wallet in the pocket of my jacket when I switch to another jacket instead of risk of stolen wallet... Besides, I still hate the lack of external water bottle stretch pocket for my flask or at least some molle attachment points for carabiners to fix the thermo bottle externally and not to risk my gadgets inside!!! To conclude with - I pretty much like my 8L Patagonia Atom Sling at colder seasons fo it's versatility and sturdiness, but it's far from being ideal EDC indeed, which push me to reach a lot of unwanted compromises alas! And as soon as I need some bigger office gadgets like 13" Ultrabook or 12" iPad Pro - I imediatelly drop this controversial 8L Atom Sling to the favor of small backpack like above mentioned Alpaka Metro 12L and it's a true bargain!

Great review, thank you!

Great review. Thanks!

My Patagonia sling did not hold up well. The material around the zippers began to pop in a few places. And the zippers kept jamming on the lip of the materials. I was extremely disappointed. I knew nothing about Osprey before. But I googled and found articles saying the Patagonia and the Osprey slings were very similar. I wound up purchasing the Osprey sling. It is much more comfortable and much more durable. I wear it every day. I toss it into my car, I fling it into a corner of my office, and I drag it about the gym. There is no comparison. The Patagonia sling began to deteriorate even though I was not taking it to the gym. My Osprey sling is still holding up well and looks just like it did when I bought it. You should follow up these reviews after using the product for a decent period of time. The Patagonia bag turned out to be crap. That caused me to find the Osprey sling. It is not even close. The Osprey sling is a much better bag. Period. You need to test this equipment more before you hand down these evaluations. I am never going to buy from Patagonia again. I called them and complained about my pack falling apart. They simply said all packs break down after being used much. Patagonia is a joke now. It used to be a decent company.

I can confirm that in the summer even the smallest chest bag will make your chest all wet. The chest produces a lot of heat. It is for this reason that in most cases I prefer a fanny pack.

I love the atom but can't use it because it can only be worn on the right and I've had shoulder surgery on that side and unfortunately can't use it. Shame.

Thank you!

Very detailed!thanks

Thank you!!!👍

IPAD MINI fits in the Osprey too!🤘😎👍

Good review, thanks a lot! :-)

Both slings seem to have been updated with improvements and I'm stuck trying to decide between the two.

They both have navy so either one works for me (lady) colorwise. I'm a boy Mom so I try not to embarrass them too much. Plus I for real don't like pink. My favorite color is blue. The Atom had purple which I know many ladies like that. I haven't tried it but I suspect that my yoga mat will secure to either one since they have the releasing strap. I can take my mat strap and loop it on the bag before closing the strap.

Thank you! Great review! In practice, does Patagonia really fit more things? Or two liters more just on paper? When they are next to each other, they appear to be the same size.

Great comparison.

Wish I could find this version of the Patagonia

Lots of help, thanks! Is the new, updated Daylite about the same (in general) as the older version shown here? I’m a petite woman and like the Osprey as an option for day hikes.

I see you have a Columbia sweater. Have you thought about doing Columbia backpack reviews? I hardly can find any on KZfaq.

How is the new updated version Atom different from the old one?

What size water bottle could you fit in these? (While sill having some room for other stuff)

Good video! thx

Sold!

6:40 will a smartphone 6,7" fit in this small pocket?

Do you think either one of these coul fit a 14" knife for example? Gonna be my bug out bag

Did the atom not have a 3 point strap ?

I'd go for the Patagonia. It has see through mesh. I don't want the whole world seeing what I am carrying. It also has a small shoulder pocket. The osprey is cheap. Don't need a bag with a small pocket that doesn't close.

Can you fit a 10” laptop in the atom ?

"ummmmm"

Could I fit a 1ltr / 32oz hydroflask in the front daylite atretch pocket?
