Mix business and pleasure while staying in your target workout heart rate zone. The Osprey Flux backpack is a compact and ergonomic solution for commuters who extend oil-free Wednesdays into the other six days of the week. It's part of the new Osprey backpack Daytool Series, a complete line of school and business packs equipped with backcountry-ready components. The Osprey Flux backpack is more oriented toward business than books, with a padded laptop sleeve and file dividers. Swap out your laptop for a hydration pack and you'll find an exit port and hose guides along the diecut harness. Along the sides you'll find a roomy pocket for your 32-oz. water bottle and a smaller quick-access compartment for your cellular phone. Aside from reduced dimensions and a regular internal organizer instead of a deluxe model, the Osprey Flux backpack is similar in features to the Osprey Focus backpack. Like all Osprey backpacks, the Flux backpack emphasizes ergonomic comfort through a molded ventilation backpanel backed by a rigid framesheet. Go light and compact without sacrificing versatility--the Osprey Flux shoulders your fluid lifestyle without compromising comfort.
Good size and functionality for a city pack.

Perfect for traveling with a laptop.
The back pack was the perfect size to hold my laptop, files, and a few necessary carry on items. My hands were free as I walked through the airport, and the bag fit just fine in overhead atorage on the plane.
Best pack I ever had
I purchased this pack in October 2004 for a 2-week vacation. Afterwards, I can't detach myself from using it for my daily commute and activities. This is one of the best packs I've ever had. Easy on the back, great organization, full features, younameit. The only suggestion I can think of for the next edition is to add more distinct reflective stripes on the front part of the pack. Perhaps if the logo is reflective, it'll be very cool.

Everything I was looking for
An amazing backpack!
I purchased the medium/large, black model. It's very, very cool (and nobody else has it yet). My 14.1 inch laptop fits perfectly inside the laptop sleeve, my mp3 player fits perfectly into the top pocket. The cell-phone pocket is very convenient. The drink sleeve easily fits a full-sized nalgene. Also, don't be discouraged by the relatively small size description. My Flux seems to be able to expand to much larger than the reported 1500 cubic inches.
I 100% recommend this product.
Step 1 - Pack SizingAll 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).
Step 2 - Hipbelt SizingTo 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.
| Torso Length | Pack Size | Hip Measurement | Hipbelt Size |
|---|---|---|---|
| > 22" | XLarge | > 36" | XLarge |
| 20-22.5" | Large | 33-37" | L or WL |

ErgoPullNearly 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).
| Men's | SM | MD | Large | XLarge |
|---|---|---|---|---|
| Women's | WXS | WSM | WM | WL |
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.
