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.

Reviews - Osprey Packs Stratos 40 Backpack

Herb Kavet - 2009-10-25

Great pack with all my favorite features in a light package
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.

in love
This is a great winter bag---winged compression straps hold snowshoes tight and at 2600 cubes (lg) it holds all my winter gear--top is roomy enough for extra gloves, hats, and food and the mesh pockets are big enough for insulated nalgenes--ice axe hangs securely--hip belt is super comfy--good job by Osprey

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..

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.
