Osprey Packs Stratos 40 Backpack

Osprey Packs Stratos 40 Backpack

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.

• Key fabrics: 210 denier double ripstop nylon, 210 x 330 shadow box nylon, stretch woven nylon with lycra, 500 denier plain weave nylon oxford
• 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
• Hipbelt includes foam inserts for maximum comfort
• Top loading access with zippered floating top pocket accommodates oversize loads
• 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
• Backpanel hydration reservoir cavity for convenient, on-the-go refreshment
• 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
• Dual ice axe attachment points
• Blinker patch for safety in low light conditions
• Horizontal StraightJacket compression straps allow for load stability when carrying small loads
• 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

GREAT PACK!
This is a great pack for a few nights on the trail. The pack is a great size and while I will probably never use the ice ax attachment loops, they serve well as additional strap points for other gear. Aircore is comfortable and provides a great little pocket to air out and dry damp clothing..

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!

Great pack at a great price
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.

Solid pack for hard-core adventures
Osprey makes great packs, and the Stratos 40 lives up to the hype. This pack is built for scrambling and some peak adventures. Can double as a daypack, but it's mostly overbuilt for a simple "afternoon walk in the woods" pack. Great pack if you need heavy duty engineering.

Sizing Chart

All Osprey packs, save the transit bags, are available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck).

To determine your hipbelt size measure around your hips, not your waist. A properly fitted hipbelt rides centered over the hipbones and needs to be very snug; after all it will be carrying the bulk of the pack's weight. The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the pads when securely tightened.

Nearly all Osprey hipbelts use an exclusive ErgoPull design. It creates mechanical advantage to provide extra leverage in cinching down the hipbelt. The ErgoPull design also draws tension along the top and bottom of the belt, not through the center, so it distributes pressure more evenly over the padding and relieves direct pressure on the hipbones.

Step 3 - Harness

Osprey Crescent & Luna, Aether & Ariel and Waypoint packs offer interchangeable shoulder harnesses. Harness sizing usually corresponds to pack size, but your best bet is to try one on. A properly fit harness should terminate 2 to 3" beneath the armpit. Webbing should not touch the body. By breaking the hook and loop connection and sliding the harness up and down the backpanel the torso length can be adjusted up to 3". (see illustration).

Once you have the correct size pack, harness and hipbelt, and the torso length set properly, it's time to put some weight in the pack (20 to 30 pounds of well distributed weight will do) and dial in the fit. First, snug down the hipbelt and harness. Connect the sternum strap (A) - position it about 2 inches below your collarbones and snug it down lightly. Finally, tighten the load lifter straps to draw the load solidly against your back. The lift straps (B) should come off your shoulders at a 45 to 60 degree angle in Osprey's ReCurve and Ethereal Suspension packs. In other models these straps serve more as compression straps and ride flatter; they may even angle downwards.

In a good fit, there should be no pressure points and no gaps between your body and the pack. With Osprey's ReCurve packs, final tweaking may involve custom fitting the aluminum stays to your back.
