Product Description

Since Osprey was founded in 1974, every single product design has passed through the hands of owner and founder Mike Pfotenhauer, who created his first backpack at age 16. In Santa Cruz, California, the young entrepreneur opened a retail shop in the front of his rental house where backpackers and travelers came for custom-fit, made-to-order packs constructed over several days by Mike himself. As the demand for the great-fitting packs increased, Osprey found itself relocating to its current home in Southwest Colorado. Today, Osprey is a melting pot of diverse personalities, backgrounds and abilities. All share the common belief that adventure is open to everyone and found anywhere.

Osprey vs. Outlander vs. Sea to Summit

Osprey vs. Outlander vs. Sea to Summit
In my quest to find the best ultralight, packable daypack for travel, I come across three different backpacks:- Osprey Ultralight Stuff Pack (18L)- Sea to Summit Ultra-Sil Ultralight Day Pack (20L)- Outlander Ultra Lightweight Packable Daypack (20L)I purchased the Osprey and Outlander pack and tried both of them for a week. I also tried Sea to Summit day pack in a nearby REI store. In the end, I choose Osprey over the other two brand, for the following reasons:- Exterior fabric:Osprey has a soft, smooth exterior fabric, which does not cringe or make noise. When fully loaded, its streamlined shape is the best of the three. In comparison, Outlander's fabric is too stiff, and Sea to Summit's fabric is too noisy. Both of them looks ugly as hell, if not fully loaded.- Weight:Osprey weights 90g, Outlander 208g, Sea to Summit 72g.- Packable size:Sea to Summit packed down to the smallest size, Osprey is only slightly bigger, while Outlander is more than twice as big, when packed into its own staff sack.- Shoulder strap:Osprey has the most comfortable shoulder straps among the three. Its shoulder straps are ergonomically designed to have the pack firmly fit to your body. In comparison, Sea to Summit's shoulder straps are the least comfortable. Outlander's straps are good, but not as good as the Osprey.Note about the sternum strap - some reviewers claim it is a must, but in my daily use I don't really feel the need for that, as long as I don't overload the pack (and you should not do that anyway).- Side pocket:Outlander has two side pockets, both of them are not deep enough to hold my 750ml water bottle securely. Osprey has one side pocket, and it is deep enough to hold the water bottle securely. Sea to Summit pack has no side pocket at all.In summary, Sea to Summit day pack is the lightest and smallest of the three, but it sacrifice too much feature and usability to achieve that, IMO it is not worth it. Outlander pack is too heavy, too big when packed down, and too noisy to carry. Osprey's pack strikes a very nice balance among size, weight and usability, and that is why it comes out on top.

Oh, this is not a backpack for heavy loads. You can use it all day long with very light loads, such as a raincoat only.

Where this shines is having it in your pocket or a small shoulder bag and if you’re shopping, you can pull it out and use that to talk. Whatever you got back to. Where are you living. It is medium plus in size and it’s kind of amazing that the pouch size is so small. It’s extremely practical. Can it carry a heavy load? Yes but the straps for your shoulders are not padded or sized for heavy load. You can pull it off if you have to though.

My wife also uses it on airplanes. It’s like a feather as long as you don’t over pack it.

I never intended to use the packing pouch when using it as a backpack. It’s at the top of the pack. It’s amazingly practical for sunglasses, cards, keys and everything else you don’t have to hunt through the backpack small area, but very very practical.

Style: Ultralight Stuff PackSize: One SizeColor: Tropic TealVerified Purchase
It was perfect light weight packbable backpack for traveling with only carry on bags. Not only it was light weight and super convenient but also I loved the color! There are a lot of review on YouTube so I recommend to check them out.

I loved the top pocket having nice size and key hook. It's so smart. It easily hold sunglasses, small travel wallet (or just small zip bag) and some random things like tickets, maps, candies etc.

Just you might want to pack enough things in the main compartment else water bottle from the side bottle holder kept dropping as you bend down.

I know it doesn't look nice to having back pack in front but I wore so for the extra security when I was in a place where I should be alerted for pickpockets. The top pocket comes right under my chin and I felt very secure and convenient too.

I got it from Amazon warehouse and wasn't sure what was the quality but it was as described, just lacking original packaging, and was perfect for me.

***Update***
I really need to be careful with the side pocket. I was putting a metal water bottle and the main compartment was almost full but yet there bottle dropped and got dent at the bottom... I still think this bag is great and won't lower the star though.

I don’t know what easy to drink from means that’s one of the five stars I can give it. If they mean that as a pocket on the side of it to put your bottle and it does so I guess that means easy to drink from. This is a nice little bag. It was deal of the day it took forever to get here I don’t know where they’re made by it took forever to get. Weighs a few ounces. Very very small nice and you can fit a lot of stuff in it. Now let’s keep in mind this is not for the hiking person who’s going to be setting up camp it’s not that kind of a bag it’s not that big and even if it was there not made for that kind of stuff it would rub up against your back too much what I love the straps that go over your shoulders are very very lightweight and very durable overall very water resistant and. . I don’t know what I’m going to use it for most likely commuting over to the work on nyc or maybe even for the gym I’m not some big hiker but I’m going to be tossing stuff in it and throwing it into my car. And if I ever need to grab it out I can just take it and pull it out. If folds up into my glove compartment and still leaves me half a glove compartment and I have a Honda Civic. I think its $35 now it wasn’t when I bought it it was on sale but the company is really good they offer a whole bunch of other stuff but let’s be honest they are not cheap. The higher you go the more expensive they are but if it’s for somebody who’s looking for light weight type stuff and if you’d be able to fold it up you can’t go wrong

Style: Ultralight Stuff PackSize: One SizeColor: Tropic TealVerified Purchase
I wanted an ultra lightweight, good looking day pack for everyday use while I'm traveling and need a smaller pack besides my kestrel 48. I ended up using this at work and while shopping at hometown. it's a great item that has its pros ad cons:
pros:

1) got in a rain, did a pretty good job considering it's very thin material
2) feels strong and durable, very lightweight, breathable.
3) Might be more comfortable than same products from other brands
4) looks really good, got a blue one.

cons:

1) Converting it into a small pack as stated is not that easy. Also it does not come with instruction how to do so safely.
2) This pack for me seems best when not loaded heavily. I put my camera, kit lens, power bank, extra battery, extra shirt and rain jacket, wallet , keys and small items, with total weight of 2.2 kg and it was ok, but heavier than that was not very comfortable while wearing on shirt. If you wear a jacket , than the straps won't dig into your shoulders as much and you can go with 3 or 4 kilos, depends on you. for me the comfort zone is 2 kg.
3) it's a bit transparent, I could see my neon green shirt from the outside
4) it does not have it's own shape and is very thin , so does not provide any protection for items inside.what I did was, I put my cloth or soft items on the bottom and on the sides than added others items on top, like my camera.

This is not a perfect bag, but I really like it anyways ( till now ) and don't regret getting it. It's not for heavy loads and easily breakable items, but it was never meant to be used for that. I use this more often than my 25 liter day pack with a mash back that I used to wear almost everyday. I'll see how this works in summer.

I do recommend this lovely osprey product if you think you need a pack like this. I don't expect others brands to have better value options for the price.

Style: Ultralight Stuff PackSize: One SizeColor: Shadow GreyVerified Purchase
Now it may not fit in most pockets, however small enough to hold on your hand or clip on to a belt loop. It’s a lot more durable than it appears, after reading reviews on the material actually being quite strong I tested it before a 9 day trip to Japan. I filled a gallon jug and stuffed a bunch of junk in the bag to test it. I jumped and ran for about a mile and no sign of it ripping or stressing, it handled the abuse better than anticipated. When I say I jumped I mean I jumped high did burpees and shook it side to side aggressively purposefully to cause it to rip, and nothing. It worked great for my trip and would highly recommend it.

I hope they add a molle attachment in future iterations. I know it’s discontinued.

This pack is very light and think and it has to be in order to fold up into a tiny ball. I feel like the place where the straps join the body aren't going to last too long unless I'm super careful. I wouldn't walk around with this holding it by the straps. The thing is, I don't think they're misleading us in any way. Again it has tj be this way to find into a bag the size of a baseball.
