Main Compartment and Top Access Pouch
Despite looking like a small, low-capacity pack due to the Rev’s somewhat floppy, softer construction materials, the main compartment holds an exceptional amount of gear. It easily fits a set of work clothes in a garment carrier, lunch, additional clothing, and even a pair of shoes, and the single top strap holds everything in place quite well.
The top access pouch (the gray area of the main compartment in the pic below) is reserved for smaller items which need a little more protection, and that aren’t needed during the run, like a wallet, identification badge, checkbook, keys, etc.
Back and Waist Strap
The back of the pack consists of tightly-woven mesh covering 1/8” of flexible, padded, breathable material. That’s it. Unlike the Manta and Stratos with their AirSpeed back panels that separate the pack from your back, the Rev comes in direct contact with your back. While still extremely comfortable, it does heat your back up quite fast.
The waist straps have wide, padded “wings” on each side where they attach to the pack. The connecting strap is narrow, non-stretchy, and the plastic buckle is small. On the outside of each wing, and within easy reach while running, are medium-sized, zippered pouches, capable of carrying a wallet, gels, energy bars, or any combination thereof. The whole setup is quite comfortable and I never once experienced any chafing or irritation in this particular area.
The shoulder straps are made from the same material as the back of the pack; waffle-like padding covered with a durable mesh material. One of the unique aspects of their design can be seen where the straps attach at the top of the pack. Rather than just have the medium-width straps rest on your shoulders, Osprey added some additional material that makes the top of the straps nearly as wide as the pack, making the pack rest very comfortably in an area that is prone to chafe and irritation, especially when carrying heavier loads.
On the left strap is Osprey’s DigiFlip™ media pocket. It holds smartphones up to 5 ½” long and 3” wide. It fit my HTC One M7 nicely, though without its Otterbox Commuter case. The pouch flips down and your phone is touch-accessible through a clear vinyl cover and the outside of the case is made from water-resistant material, as well, so the phone is completely enclosed and weather-resistant. On the outside of the DigiFlip pocket is another stretchy, storage pouch.
The right strap has two narrow, overlapping stretchy pouches which can hold anything from a flashlight, to gels, bars, or pens and markers. Each strap has two attachment loops above the pouches for routing the hydration hose, or attaching items such as blinking lights.
Connecting both shoulder straps horizontally are two stretchy, adjustable sternum straps. Both can not only be adjusted left and right, but can also be slid up or down along the straps. The topmost chest strap has a magnet on the buckle, and is used to hold the mouthpiece of the hydration hose while in use.
The Rev comes with a 2.5L Hydraulics™ LT bladder that is designed to keep the water from annoyingly sloshing around, as well as to keep the bag flat and from balling up in the bottom of the pack.
The hose has a cool quick-release feature, which allows it to disconnect from the top of the bladder, and end of the hose contains a magnet that attaches to the upper sternum strap buckle, which keeps the bite valve close to your mouth while running.
The backpack has a designated hydration storage section within it that is zippered at the top and rides close to your back when secured. The bladder slips easily in and out and since you can disconnect the hose, it makes for quick refueling stops along the trail.
