Osprey Stratos 40

Hiking & Camping > BackpacksRated: ***** by 37 reviews.

Altrec

Big enough for an overnighter, small enough for day trips, the Osprey Stratos 40 Backpack is a do-it-all all-star of mid-size packs. The sophisticated AirCore suspension offers support that easily handles loads up to 30 lbs. and the hipbelt even does double duty, providing small mesh pockets for handy storage of snacks, sunscreen, etc. Varied load configurations are a cinch thanks to side pockets, compression straps, and a floating top pocket. Jam a water bottle into a side pocket, and then later in the day use the same side pocket and compression strap to carry your trekking poles. Meanwhile the floating top pocket extends to accommodate gear intensive endeavors. A zippered left front pocket allows for access to the main compartment, often a faster method of reaching buried gear than digging down from the main top access.

Features:

  • AirCore suspension consisting of twin 5mm vertical composite struts with a center stabilization disc anchored into top and bottom high impact polycarbonate wings, tensioned contoured mesh backpanel, and SpacerMesh shoulder harness (includes adjustable sternum strap) and hipbelt
  • Backpanel hydration reservoir cavity for convenient, on-the-go refreshment
  • Blinker patch for safety in low light conditions
  • Capacity: 1,800 cu. in. (30 l) in size small, 2,000 cu. in. (32 l) in size medium, 2,200 cu. in. (34 l) in size large

  • Hipbelt includes foam inserts for maximum comfort
  • Horizontal StraightJacket compression straps allow for load stability when carrying small loads
  • Key fabrics: 210 denier double ripstop nylon, 210 x 330 shadow box nylon, stretch woven nylon with lycra, 500 denier plain weave nylon oxford
  • Left front zippered pocket also allows for access to the main compartment
  • Mesh pockets in hipbelt for handy storage of small items used throughout the day
  • Side panel compression straps and stretch woven pockets for easy transport of trekking poles, fishing rod, pickets, etc. These pockets also provide quick access storage for water bottles
  • Top loading access with zippered floating top pocket accommodates oversize loads
  • Weight: 2 lbs. 12 oz. (1.25 kgs.) in size small, 2 lbs. 14 oz. (1.30 kgs.) in size medium, 3 lbs. 0 oz. (1.36 kgs.) in size large

Stratos goes to Germany

Rating:*****

I researched many backpacks as I was heading to Germany for a few weeks. Here is what I was looking for:

Q) Most importantly a pack that I could carry on (or check at the plane, not as baggage)

R) A pack that could hold about a week's worth of clothes and minimal travel items.

S) A pack that would carry well once fully loaded, that wouldn't kill my middle-age back

T) Nice looking, with pockets

After doing all of the research I made the decision to go with the Stratos 40. I just came back from Germany, and have to tell you it was the perfect size and companion as I moved from Munich to Cologne, via train, car, plane, and hiking. It had room enough for everything I needed and the additional room left for some small items purchased along the way. On smaller commuter flights it had to be checked at the plane, but on the international flights the Stratos 40 fit perfectly in the overhead compartment. I didn't hear one complaint from any airline personnel about the size or weight. My traveling companion decided to take conventional luggage, and it was the WRONG thing to do, as I watched him having to lug it around the airport, wait for baggage check, not to mention the difficulties he had as we moved around by rail. I do wish the Stratos had a little better access, but understanding it IS a backpack it has been manufactured using quality material and looks like it will last a long time for me.

I plan on using the pack for more conventional outings, camping, and hiking- but it was PERFECT for what I needed in Germany and abroad.

Great pack for overnighters or weekends

Rating:****
I got this pack for a song at a swap meet, and have not looked back. I have owned several packs over the years, Dana Designs, ArcTeryx, Mountainsmith and others, and for a comfortable overnighter or a quick weekend, this pack delivers just what you need. The side stretch pockets are spacious enough for water bottles or a jacket, the stretch front pocket can hold that soggy tent fly, and the hipbelt pockets keep your camera, GPS, compass, lip balm and a few Clf bars at your fingertips. The suspension is top-notch, as is the ventilated back panel. The side-zip access is great for getting to your gear towards the bottom of the pack, and the top lid is big enough to hold your smaller items, but small enough to not flop around when understuffed. The pack also has the ability to cinch WAY down thanks to the innovative front compression straps, which can also hold a snowboard or snowshoes with ease. The 2lb 14oz weight(medium) is practically unnoticeable when stapped to your body. The main drawback I have encountered is, due to the flexed shape of the frame, a full water bladder cuts into the overall capacity of the pack. You can get around this by stashing your bladder between the trampoline mesh backpanel and the pack, but then you lose some of the ability to circulate cool air behind your back, and accesing that space through the provided zip can be a hassle. Other than that, this pack will give you a lot of bang for your buck, and the usual Osprey quality is highly evident.

would recommend

Rating:*****
I purchased this 2400ci pack to (1) replace a 2000ci pack and (2) to move it away from my back. I tend to carry enough on my day hikes to ensure comfort and safety should I have to spend a night out, and I never seemed to have enough room. I have not yet used the osprey on a day hike - but i have packed it as I normally would the 400ci makes a big difference. I day hike in the inland areas of southern california where the temps in summer can reach 90+ F. My previous pack, although about 1 pound less in weight, would be saturated - as would my back. My hiking buddy who has one of these packs swears by it and was always dry during our hikes while I was wet. I am looking forward to using this on my next dayhike!

fits all that you need and keeps your back cool

Rating:*****

This is a great pack. I did some serious looking for a medium capacity pack with all the right pockets and that could compress nice and small. This pack has been great for traveling and for camping, i would highly recommend it.

The only thing that threw me off is the sizing. I am normally a medium in all that i buy. According to my torso length, I need a small in this bag. I tried a small Osprey in the store and indeed that is what i needed. Since the torso i s not adjustable it VERY important not to get a pack that is too long. The straps on the pack (as you will read in other reviews) are quite long. I had no issues sizing it to myself, even though according to the other measurement the pack would be too small.

Most Comfortable Pack

Rating:*****

This is the most comfortable pack I have found so far. It is great for long weekends. I love all of the features on this pack. All the pockets and easy access points throughout the bag. The hip belt pockets are perfect for an energy bar and multi-tool or iPod. But it packs away everything you need. I have carried 30+ lbs. for a weekend and the pack does not feel like it weighs as much. Also I am a bigger guy and usually sweat a lot with a bag of this size on, the mesh back panel makes it much more comfortable, especially after 8-10 hours of hiking. The air flow system in the back panel will keep you fairly dry and comfortable during your hike. This is a great pack for day trips and weekends!

Great pack at a great price

Rating:*****
I use this pack for carrying my climbing gear and love it. The internal volume is great, the access to the top storage is key and easy to get into even while wearing the pack. The external straps are perfect for securing my rope and the stretch pockets on the outside are great for extra clothes or bottles. The suspension system is great and the straps are comfortable. I especially love the AirCore feature since it gives a simple protected space for your hydration and keeps your back cool and dry. The pack is quite durable and well-built. Storage in the waist straps is excellent as is the ease of adjustment. I recommend this pack for anyone looking to carry a moderate amount of weight moderate distances.
Travis Lent at Altrec on 06/23/2008

Great all around pack

Rating:*****

Love the size, the color (black), the fit (I am 6'2 205 size large pack), and the air core back is great in the summer. This fits everything I need for any summer outing and short winter outings. For the intended use of a daypack this has more than enough space. For the lightweight hiker this is a great pack that can hold it all for at least a weeklong summer trip. The only downside is that you can't remove the top pocket and the stretch sides are hard to get bottles out of when the pack is loaded. Overall good load distribution, 30 lbs is definitely reaching the limits of my comfort level with this pack. 22-26lbs is the sweet spot for me. Highly recommend.

"Exquistito!!"

Rating:*****
I got the tangerine pack because recent studies conducted at MIT indicate that this color drives the ladies crazy. I can barely climb a mountain without getting attacked. I also like it because it is thoughtfully designed, well made and with a 30lb load, very comfy. It is also important to note that Andy Warhol wore a pack like this when he discovered Campbell's soup. The hip belt is both functional little zip pockets for all of my condoms and comfortable. I researched long and hard for a pack this size that would meet my needs within a reasonable price range and this one did not disappoint. Moosejaw service was outstanding as well. A blond woman in a mini skirt delivers the package ri

Great pack with all my favorite features in a light package

Rating:*****
I travel the world by bike and till now used a custom made pack with a host of little features like zippered compartments in the waist strap to keep ready cash and mesh back to keep cool in hot climates. Being unable to find someone to rebuild my worn out custom pack I checked what was available ready made. To my delight the Osprey 40 had virtually everything I had in my custom job at lower weight and increased size. My only disappointments were minor.The broad top limits the rear vision from my bike mirror. It doesn't have a built in rain cover but this is easily remedied by carrying one in the large main compartment.

Stockier Torso....

Rating:****

With all its dangling strap ends and a back frame that takes getting use to, Not a bad (2400cu.in.Backpack)..It can surprisingly pack away the gear.
The back panel hydration cavity is alittle hard to enter with a bladder bag. The wasit belt system could be alot simpler doing away with the two belt system. The frame could be made alittle more wider(contoured for a more stockier torso.) Had forgotten all about the side entrance zipper on the left side of the bag, handy little unit.. Enough strap on the compression wings to place a light sleeping bag there. Can do a over nighter with this outfit....Only time will tell what it can handle....

"solid pack with minor pros and cons"

Rating:***
huge props on materials, construction, and quality practical and classic design - this size is PERFECT as an ascent pack. enough for food, layers, and a few safety items. but truthfully ... - too many straps ... too easy to catch on stuff and get caught - the pack straps are a bit too close together on the top and the curvature where the sternum strap is ... when weighted down, gets a bit too rubby and could cause a hot-spot - need access to the bottom. ... and what happened to the single clip buckle on the front like the smaller one? less is more and i liked how the 1 clip design allowed for easier access and less clutter this would make an awesome adventure racing pack ...
Tery at Moosejaw on 07/11/2008

SUFFICIENT....

Rating:***

Its a nice little backpack. But the backpack framing system(Arch on the inside.) Takes up way to much room inside of the main compartment. And waist belt set up is another draw back, One belt would seem to be sufficient and the straping system way to many loose ends dangling and the hydration system(Exterior sleeve)alittle hard getting the water bag in and out of it... It would make a nice little day pack....
