Osprey Stratos 50 Internal Frame Backpack

August 27, 2019


The largest of the Stratos series, the Osprey
Stratos 50 is a great ventilated option for overnighters, weekend trips or week long backpacking
trips. Let’s take a look at all of its features. We are going to turn the pack around and take
a look at the suspension system in play here. So we have got Osprey’s Airspeed Suspension
System. It is a really nice, light-weight and super breathable suspension system. You
have got a tensioned mesh back panel and a light wire aluminum frame around the exterior
of the pack. The tension mesh is actually suspended off of the back panel so you have
got spacing between the actual backpack contents and where your back is going to come into
contact with the pack. So you have got really good breathability, really good ventilation
throughout this back panel, really good moisture wicking and just overall venting, so nice
system in play. We have got contoured foam shoulder straps.
They are nice and padded shoulder straps and they have got a nice breathable kind of perforated
foam here so you have got good breathability and comfort throughout all of the shoulder
straps. Down in the hip belt we have got that same
system. You have got nice padded hip belt wings and they have got nice perforations
in them, as well, to provide more breathability. And the mesh lining there is going to help
to wick moisture and pull away any sweat that may build up. So you have got really, really
nice padded shoulder straps and hip belt with a nice tensioned mesh back panel for optimum
breathability. Turn the pack back around. We are going to
take a look at how we access the contents. So we have got kind of three access points
with the Stratos 50. You have got a traditional top loading hood style backpack. So if we
take off the hood we have got a nice, you know, spin drift collar up here. So just draw
that cord back. And you have got a really nice wide, opening at the top there. Going
to give you easy access to those items that are on the top of the pack. Now the hood is removable so you can take
that of and just use this spin drift collar as your top if you want to shave some weight.
But that hood does provide a little extra pro-tection for the contents of the backpack. Another access point we have got here is the
front zipper pocket. So this front zipper pocket you see opens up and you can actually
access all the contents of the backpack di-rectly from the front zipper. So if you don’t want
to open up the hood and do all that hassle, you can access the contents from that front
double zipper system. And that goes all the way around down to either side. So it kind
of treats it like a suitcase almost. It is a big U shaped zipper. So a nice zipper system
on the front of the pack. We have also got a sleeping bag or a lower
compartment on the pack. So down at the bot-tom here we have got a nice system in play. You
can zip that up and open it up. I have just got a hammock in there right now, but this
is a separated compartment so it doesn’t, you know, work with or attach to the top compartment,
this system here, this material is fully stitched in. So it is a completely separated compartment.
You can’t really make them one compartment. So still a nice feature, adds a little bit
of versatility to it. You can keep some items down here that you may want to get a little
more quick access to. So that is a nice addition. Some other features we have got with the Stratos
50 include some removable sleeping pad straps so down at the bottom here we have got these
two straps which you can attach here. You can lash a sleeping pad to the outside, use
them as extra compression if you choose to or remove them if you don’t plan on using
them. So nice versatility with those straps there. A feature that adds a lot of value to the
pack is the fact that it comes with a built in rain cover. So at the bottom here you have
got a little tab that just says rain cover. It is a little water droplet. And you have
got a zipper there. It is kind of a hidden zipper. And inside is a removable, detachable
rain cover. So most packs you have to buy this separately as an add on. With the Stratos
50 it is included in the bottom of the pack, so a nice addition. It adds a lot of value
to the pack. Moving up we have got a nice tool loop with
kind of a stowaway bungee here. So keep-ing with the streamlined design, that bungee is
tucked away. But you can simply kind of take it out and it will come out of this little
pocket here and you have got a nice bungee system that is tucked away, hidden nicely
so it doesn’t get snagged on anything. If you are hiking on a dense forest train or
if you are climbing it won’t snag up on any rocks, trees, et cetera. On the sides we have got two mesh pockets,
so stretchy water bottle pocket on this side here. And we have got inside out compression
underneath. So on this pocket the com-pression is routed against the backpack to keep the
contents nice and simple and secure. On this side we have got the inside out compression
on the outside. So you can actually lash gear to it, keep everything nice and snug and secure
so my trekking poles here are held firm by that inside out compression strap, so a nice
system with the compression on the pack there. We do have some hip belt pockets in play on
the backpack, nice zippered hip belt pockets. You can store some small items there like
head lamps, cell phones, anything you might want to get to quickly, snacks, granola bars,
et cetera, really two good pockets there that give you some weather resistance and easy
access to good items. This pack is hydration compatible as well.
So you have to an H20 port on the side here and there is an internal sleeve that allows
you to stow a hydration bladder. It is not in-cluded. They are sold separately, but you
can use them with this system, so a nice benefit to the pack there. On the hood we do have multiple pockets. So
on the back of the hood where we has got two pockets. One of them is fairly small. I have
just got a lightweight jacket in there and a first aid kit. Bottom one is a little bit
more sizable. So I have got a book in there now. You could fit some other items, maps,
maybe some food, anything you might want to get to a little more quickly. And on the underside
of the hood there is a mesh pocket for, again, some smaller items. If you want to keep your
keys there or things you want to keep away, but not get lost in the pack, you have got
a little pocket there as well. Finally you have got a little bit more compression
at the top of the pack. So you have got these two straps, one on either side, that come
around to the front and they snap down and you can really use those to compress the load
if you choose to. And the straps that attach to the actual hood can be used as compression
straps as well. So you have got a nice strap there you can yank on, get some extra compression.
And this system here you can also compress the load. So you have got really streamlined,
really simple design and really effective at really compressing smaller loads or expanding
to accommodate larger loads. While being incredibly ventilated and breathable,
the Osprey Stratos 50 is a great option for overnighters to week long backpacking trips.

  1. Does the Osprey Hydraulics fit inside it? If so can you show me because I have this bag and the Osprey Hydraulics but it doesn't seem to fit.

  2. This might be a stupid question. But how come the dimensions of this pack are smaller than the talon 45. If this is a 50L and the talon is a 45L??

  3. Hey Backcountry, thanks for the awesome review of the pack. I want to use a 40-50L pack this summer for international travel rather than a suitcase. My trip is 2 weeks. If I don't want to check this in, any idea if this pack passes regulations and can be used as a "carry on"? Thanks.

  4. would this bag also work as a big bag for work?
    getting my big lunchbag in, 3 pair of gloves, some hearingprotection, a safety visor, a bulky medicbag and heaps of other stuff…

  5. Hey! I'm looking at a backpack for long-term travel (staying in hostels, not camping) and I'm looking at this backpack, the atmos 50, and the aether 60. Do you have a personal favorite between the three? I'm looking to stick to smaller packs if possible. I think I could fit the 50l as a carry-on without raising too many eyebrows, although I'm not positive. Thanks for your help!

  6. Hi, I am going on a 5 day hike with my friends in mid to late August in Georgia on the Appalachian Trail. This is my first ever hike, would this bag be a good bag for this trip?

  7. Really nice review! I want to buy this pack for a 6 day hiking trip on the W trek in the Patagonia. Do you think this pack would be enough for a trip like that?

  8. What Hammock was that at the bottom? Got any good small tents that would fit in this pack and not be too big? I've got the same pack just black

  9. Osprey have redesigned their packs but i prefer this version of Stratos 50. Is this version still for sale?
