Osprey Packs Stratos 18 Backpack

Osprey Packs Stratos 18 Backpack

Built for a full day of motion, the Osprey Stratos 18 backpack featuring the AirCore suspension keeps the air circulating behind the back. Even the most driven hiker will notice the increased range of comfort when the temperature rises. Hydration options are also abundant on the Osprey Stratos 18 daypack. Bottles fit nicely in the two stretch woven side pockets and a hydration bladder conforms nicely in the cavity immediately behind the AirCore suspension. Yet another option is to place a bladder in the internal hydration sleeve and then routing the tube out one of two exit ports, depending on personal preference.

• AirCore tensioned mesh backpanel and suspension
• Sewn-in contoured spacer mesh shoulder harness
• Spacer mesh hipbelt with pockets
• Front panel access
• Backpanel cavity for versatile packing options
• Large, zippered front pocket
• Front and side stretch woven pockets
• Internal hydration sleeve with dual exit ports
• Ice axe loop
• Capacity: 1,000 cu. in. (16l) small/medium, 1,100 cu. in. (18l) medium/large
• Weight: 2 lbs. 8oz. (1.12 kgs.) small/medium, 2 lbs. 9 oz. (1.18 kgs.) medium/large

Looks small but fits a lot
My first reaction when I opened the pack was: ‘Holly cow, what am I going to do with this?'. The bag looked way too small for my needs. I.e. I needed a pack for occasional hikes but specially, I needed it for an urban context where I could put my laptop and a few books. To be honest, the stratos 18 looked so small that I even didn't try it, I only looked at the bag and decided to send it back. However, I eventually resolved to give it a go and I was extremely surprise when my Macbook was comfortable lying there. And more!! There was space for 4 books. But even more, you can put tons of stuff in the suspension area. Finally, the bag is so well designed that you don't feel the heavy load that you are carrying.

good day pack
Comfortable, and shorter torso great for women. The Air Core can be used for water, saving space. Convenient extra pockets on waist. Only downside is the Air Core is convex and takes away from some of the storage space.

Is this Handy? - Yes - No

Unbeatable fit
This pack fits like a glove, and carrys the weight extremely well. The pack is also a winnerwhen it comes to versatility - A 2 liter bladder can be used INSIDE of the AirCore void to allow more room inside the pack. Best small daypack that I have ever used.

Good backpack
I have used this pack for about 3 months. It has worked well and stores a lot of stuff. Love the elastic pockets on the sides and front. It has two options to carry water. Only complain is that the top pocket zipper did delaminate.

Is this Handy? - Yes - No

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.
